Link Microtek has announced the Triquint high-efficiency, low-cost 7 x 7 x 1.3mm quad-band GSM GPRS power amplifier module (PAM). The TriQuint TQM7M4022 PAM provides advanced internal voltage reference and power control functionality in a low pin-count package compatible with existing phone PCB design and manufacturing techniques.
The design uses the high integration features of TriQuint's second-generation InGaP HBT 150mm process to minimize application circuit complexity. Only two external components are required to complete the application circuit in most phone designs, and the module's low pin-count of 17 ensures good solderability and ease-of-use in PCB design and assembly.
The TQM7M4022 offers a highly competitive quad-band RF and DC performance over temperature, process and voltage, including a Pout of 35dBm for the GSM850/900 band and 33dBm for the DCS/PCS band.
