Small and efficient base stations are needed as wireless service providers hope to extend their coverage, and the low-cost model RFPA2089 power amplifier from RFMD is an ideal driver stage for these systems. It is a single-stage indium-gallium-phosphide (InGaP) amplifier housed in a SOT-89 package with frequency range of 50 to 2700 MHz. It provides 17.6 dB gain with 3.9 dB noise figure while consuming only 138 mA at +5 VDC.

The amplifier delivers +24 dBm (0.25 W) typical output power at 1-dB compression with an output third-order-intercept point of +38.5 dBm. Suitable for driving base-station transceivers and for use as an intermediate-frequency (IF) amplifier, it can handle input-power levels to +11 dBm and operating temperatures from -40 to +85°C. It is meant for linear operation, with -60 dBc adjacent-channel power ratio (ACPR) at +13 dBm WCDMA channel power. Prices start at only $1.84 each for 750 pieces.
