ALM-32120
0.7GHz - 1.0GHz 2 Watt High Linearity Amplifier
Data Sheet
Description
Avago Technologies' ALM-32120 is a high linearity 2 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. All matching components are fully integrated within the module and the 50 RF input and output pins are already internally AC-coupled. This makes the ALM-32120 extremely easy to use as the only external parts are DC supply bypass capacitors. The adjustable temperature-compensated internal bias circuit allows the device to be operated at either class A or class AB operation. The ALM-32120 is housed inside a miniature 7.0 x 10.0 x 1.1 mm3 20-lead multiple-chips-onboard (MCOB) module package.
Features
* Fully matched, input and output * High linearity and P1dB * Unconditionally stable across load condition * Built-in adjustable temperature compensated internal bias circuitry * GaAs E-pHEMT Technology[1] * 5V supply * Excellent uniformity in product specifications * Tape-and-Reel packaging option available * MSL-3 and Lead-free * High MTTF for base station application
Specifications
