RF3A SP0T ANTENNA SWITCH MODULE - QUADBAND GSM, QUADBAND UMTS Package Style: QFN, 26-pin, 3.0mm x 3.mm x 0.5mm GSM Rx Features Very Low Loss Best in Class Harmonic Attenuation with Integated LPF: ETSI Compliance Exceptional Linearity Performance Lowest BOM Cost and Small Solution Symmetrical GSM Rx Ports Allow Ultimate Flexibility for Use With Any Transceiver Symmetrical UMTS Ports Allow Versatility for Use With Any Transceiver SPT and SPT Operation with No Loss in Performance GPIO Interface and Compatible with.v Logic (VCTL-High Min =.3V) Small Footprint, 3.0mm x 3.mm, 26-Pin QFN Applications Cellular Handset Applications Multi-Mode GSM, EDGE, WCDMA Applications GSM/GPRS/EDGE Switch Applications Cellular Infrastructure Applications GSM Rx2 GSM Rx3 GSM Rx UMTS UMTS2 UMTS3 UMTS/GND GSM 50/00 GSM 00/00 Product Description Ordering Information Functional Block Diagram Charge Pump/ Decoder A B C D VDD The RF3A is a single-pole ten-throw (SP0T) Antenna Switch Module. Very Low insertion loss along with excellent linearity performance achieved by RF3A makes it ideal for multi-mode GSM, EDGE, and UMTS handset applications. This module builds upon RFMD s phemt Switch technology and integrates low pass filtering on the GSM transmit paths thus avoiding the need for external harmonic attenuation. This module also integrates a decoder and is compatible with +.V control logic. RF3A is packaged in a compact 3.0mm x 3.mm x 0.5mm, 26-pin, QFN package which allows for a small solution size and lowest BOM cost as it does not require external DC blocking capacitors when external DC voltages are not applied to device ports.

Shielding cans covering the switch are not required, and they can be in close vicinity to the PA. The switch can be mounted on a flexible PWB. Application Diagram and Guidelines Decoupling capacitors on the control pins protect the control circuitry from possible RF leakage. A 00pF decoupling capacitor is recommended on the V DD line. The value of L will depend on the Contact Discharge rating which needs to be achieved for the application. In SPT mode, TRX can be used by terminating any other unused port to Ground. Electrical Test Methods The electrical parameters for the switch are measured on test PWB provided by RFMD. The test PWB includes means for decoupling RF signals from control signal port (shunt capacitor at control signal ports). All measurements are done with calibration plane at switch pins. The effect of test board losses and phase delay are removed from the results by calibrating using the calibration board.

RF3A Theory of Operation Product Description The RF3A is a SP0T Switch Filter Module (SFM) with fully integrated dual Low Pass Filters on GSM Transmit paths and an integrated decoder/charge-pump. This simplifies the phone design by eliminating the need for discrete harmonic filters, switches and possible matching components. The GSM RX ports of this module have symmetrical performance and hence the Rx branches can be used interchangeably from 6MHz to 0MHz which allows for ultimate user flexibility. Integrated filtering provides ETSI compliant harmonic suppression at the antenna port even under mismatch conditions, which is important as modern antennas today often present a load that significantly deviates from nominal impedance. This module also features an integrated charge-pump/decoder which allows for excellent linearity performance even at.v control voltage. The decoder allows the switch to be controlled in any of the specified ten states as defined by the control logic on page using general-purpose I/O control lines.
