Typical Applications The HMC423MS8 / HMC423MS8E is ideal for: Base Stations Portable Wireless CATV/DBS ISM Functional Diagram Electrical Specifications, T A = +25 C Features Integrated LO Amplifi er w/ Pdiss <5 mw Conversion Loss / Noise Figure: 8 db Low LO Drive: dbm Input IP3: +15 dbm Single Positive Supply: 3V, 15 ma General Description The HMC423MS8 & HMC423MS8E are double balanced mixer ICs with integrated LO amplifi ers. This mixer can operate as an upconverter or downconverter between.6 GHz and 1.3 GHz. With the integrated LO amplifi er, the mixer requires an LO drive level of only dbm, and requires only 15mA from a single positive +3V rail. The mixer has 8 db of conversion loss, an input P1dB of +8 dbm and an input third order intercept point of +15 dbm at 1.3 GHz. Parameter IF = 1 MHz LO = dbm, Vdd = 3V Units Min. Typ. Max.

One external RF bypass capacitor (1, pf) is required. This pin is DC coupled. For applications not requiring operation to DC, this port should be DC blocked externally using a series capacitor whose value has been chosen to pass the necessary IF frequency range. For operation to DC, this pin must not source/sink more than 18 ma of current or die nonfunction and possible die failure will result. This pin is DC coupled and matched to 5 Ohm from.6-1.3 GHz - 282 One Technology Way, P.O.
