PASSIVE COMPONENTS
passive components Passive Components and Coaxial rigid line D.M. produces a wide range of accessories for professional broadcasting applications, we may supply almost all the items (elbows,reducers,flanges,coupling elements etc.etc.) you need between transmitter and antenna system. Our devices are built in alluminum,brass and copper, and have chemical ( i.e. alodine) or galvanic (silver) surface treatments, to improve the R.F. performances. All the components are obtained starting from a single solid piece of alluminum or brass, and some items,i.e. elbows, are manufactured by fusions. The components dimensions refers to IEC 339/EIA standards, and they may be coupled with components of others suppliers,if also these ones are built according to the over reported standards. PLEASE READ CAREFULLY:In case of order,please always specify, if the items must be used for outside or inside applications, because the solutions are different. The clamping (unflanged) configuration may never be used for outside applications. Typical arrangement scheme of various passive components Legend of the scheme A) Ancor insulator connector (inner) B) Flange with clamping connection C) Elbow with clamping connections D) Coaxial rigid line E) Straight adaptor F) Elbow one side flanged the other with clamping connection G) Flanged elbow Coaxial Rigid Lines Our C.R.L. are in copper, and are comply with IEC 339-2 -EIA standards. The bars' maximum lenght (for shipment reason) is about 3 mt, around 10 feet, ( the lenght may vary between 2,80 through 3,2 mt.). Normally the standard items are sold without spacers (in PTFE-Teflon) inside, because usually our customers cut the line in many short pieces ( the lenght is often less than 1 mt, around 39"), instead if you have to use the line in pieces with a lenght greater than 1mt. (but consider that this value depends on the C.R.L. diameter ), it's necessary to install the spacers inside the line, to avoid the inner pipe downswing, making worse the VSWR. PLEASE READ CAREFULLY: Customers are kindly request to specify, on their RFQ, the employ conditions of the rigid line he wants to order, so in this way we are able to suggest the right configuration to choose, furthermore when the total lenght exceed 6 mt, ( around 20 feet), and the connecting system needs many accessories like several elbows-reducers-straight adaptors etc.etc., it could be necessary to use some line matchings to recover a good R.F. performances. If Customer doesn't specify anything, we'll delivery two coaxial tubes. 25/02/2004 Via Fontanelle di Bardano, 20-019 Orvieto (TR) - Italy

ELBOWS Delta Meccanica manufactures many elbow types to respond to the different applications customers may encounter during installation. Flanged elbows : are female, and both flanges swivel. Unflanged elbows: connections are male, so it's possible to connect directly the rigid line, without adding other coupling elements. This device cannot be used for outdoor installation. Unflanged-Flanged Elbows : this device has a side unflanged, where it's possible a direct connection with the rigid line, the other one is flanged. This is a very useful and cheap solution. This device cannot be used for outdoor installation.

DIRECTIONAL COUPLERS
Directional Couplers Directional couplers Directional Couplers are equipments designed to perform important Broadcasting measures, like Return loss, RF power, frequency monitoring and filters' performance; furthermore signals coupled from transmission line can be used for alarm circuits. All the above mentioned measurements are performed, when necessary or continuously monitored, maintaining the system on duty. Our Directional Couplers are "in line", and are equipped with one probe, or more probes according to the measurements performed by the customer. With one probe it is possible to measure forward and reverse power only changing the external load's position. The probe can be adjusted in angle and in hight, to obtain the desired value of coupling (between -70-30dB) with high directivity (>30dB). (1) more probes can be supplied on request 04/03/2005 Via Fontanelle di Bardano, 20-019 Orvieto (TR) - Italy
HYBRID COUPLERS
Technical General Overview A 3 db Hybrid Coupler is a device that allows to divide, or to add, the RF power. When it works like a divider (see fig.1), the input power is divided in half (-3dB), every half will have a phase difference of 0 and -90 related to the input power; on the other port no power there will be (insulated port). In reality Hybrid Couplers are designed in wide-band, for which the division factor is not exactly -3dB, but will follow the outline of the curves reported on fig. 2 (this diagrams refers to an F.M. Hybrid Coupler), and the insulated port it will be closed, using a suitable dummy load. Divider fig.1 When the Hybrid Coupler works like a combiner, it is possible to add the input powers (power 1 and power 2 - see fig.3) provided that they have the same frequency the same power and be dephased of 90 coupling factor fig.2 As we already said, in reality the wide-band Hybrid coupler will not add exactly the two powers, but a portion of power (-30 db) will be present on the insulated port. Furthermore working like a combiner, it is necessary to consider that, one of the two input powers could fail, in this situation, on the insulated port, it is possible to have half of the remainig power, for this reason it is necessary to close the insulated port with a dummy load of a power at least equal to the half of the one entering on one of the ports (i.e.: input 1 = 1kW. input 2 = 1kW Dummy load = 0) Our standard version is crossed version we may supply, on request, also the parallel version. combiner fig.3 16/04/2004 Via Fontanelle di Bardano, 20-019 Orvieto (TR) - Italy

MOTORIZED COAXIAL SWITCHES Our Motorized Coaxial Switch are designed for Broadcast applications, they may be employed as dual ports, DPDT, to connect two signals (i.e. main transmitter to antenna, stand by transmitter to dummy load) or just one, SPDT. More Switches may be connected among them to satisfy complex switching unit, or in addition to manual Patch-Panel. Each device has two microswitch systems (signals and interlock) to indicate the switch position. Manual operation, by means of a rotating knob, may be performed in case of power supply failure, or other breakdowns. The contacts rotation is driven by an high torque electric motor, connected to a reduction gear, switch over time is about 3". Delta Meccanica may supply also the control logic unit. Our switches guarantee a great reliability and the average isolation between inputs, is better than 60 db.

PATCH PANELS
Coaxial Manual Switch Patch Panels Patch Panel Delta Meccanica designs and produces a large range of Coaxial Manual Switch Patch Panels. According to specific Customers' requirements it is also possible to produce special configurations. The Patch Panels are built with the best materials used for broadcast devices, in particular the body of the links are manufactured in light alloys and brass, and the contacts are fingers in beryllium copper, these contacts realize a low insertion loss and, at the same time, warrant a very good R. F. performances lasting for all the patch-panel life. Our simple, reliable and easy to use disconnecting system doesn't need of any tools, permitting to perform the change over procedure in a short time. All the components have a galvanic surface treatment to give the best protection against corrosion, and to guarantee the best R. F. performances. In addition all the patch panels are supplied with micro-switches to assure the interruption of transmitters' power supply during the disconnecting operation.

SWITCHING UNITS Patch panel/power divider for dual antenna system : are becoming more and more requested in the plants were is required greatest reliability, and transmission stop cannot acceptable. In practice, in normal working conditions, signal goes -crossing trough a patch panel- to a power splitter, is splitted down in half and each half feeds an antenna system composed by 2 self reliant units. This solution permits: in case of failure (or for maintenance reasons) of one of the 2 units, the other one may still work at full power, because the whole RF signal is switched on the operative antenna unit, by passing, by means of the patch panel, the power divider included on the system. We delivered to a Dutch customer an equipment that manages three switching systems for as many antenna systems.
