ALM-31122 700MHz - 1GHz 1-Watt High Linearity Amplifier Data Sheet Description Features Avago Technologies' ALM-31122 is a high linearity 1 Watt PA with good OIP3 performance and exceptionally good PAE at 1dB gain compression point, achieved through the use of Avago Technologies' proprietary 0.25um GaAs Enhancement-mode pHEMT process. x Fully matched, input and output All matching components are fully integrated within the module. This makes the ALM-31122 extremely easy to use. The adjustable temperature-compensated internal bias circuit allows the device to be operated at either class A or class AB operation. The ALM-31122 is housed inside a miniature 5.0 x 6.0 x 1.1 mm3 22-lead multiple-chips-on-board (MCOB) module package. x High linearity and P1dB x Unconditionally stable across load condition x Built-in adjustable temperature-compensated internal bias circuitry x GaAs E-pHEMT Technology[1] x 5V supply x Excellent uniformity in product specifications x Tape-and-Reel packaging option available x MSL-3 and Lead-free x High MTTF for base station application Top View VCTRL GND GND 18 19 20 21 22 1 16 2 NC x 31.6 dBm Output Power at 1dB gain compression GND 4 GND GND 13 5 RF_IN GND 12 11 10 9 GND 8 7 6 GND 3 14 NC 15 GND GND GND GND x 47.6 dBm Output IP3 VDD2 GND GND RF_OUT 17 x 15.6 dB Gain GND 31122 WWYY XXXX GND GND 900 MHz; 5V, 394mA (typical) VDD1 5.0 x 6.0 x 1.1 mm3 22-lead MCOB GND Specifications GND Component Image Bottom View Notes: Package marking provides orientation and identification "31122" = Device Part Number "WWYY" = Work week and Year of manufacture "XXXX" = Last 4 digit of Lot number x 52.5% PAE at P1dB x 2 dB Noise Figure Applications x Class A driver amplifier for GSM/CDMA Base Stations. x General purpose gain block. Note: 1. Enhancement mode technology employs positive gate voltage, thereby eliminating the need of negative gate voltage associated with conventional depletion mode devices.
