Analog Devices launches GaAs PHEMT driver amplifier
Analog Devices has introduced a medium-power, distributed driver amplifier, which operates between 24 and 35GHz. The HMC1131 amplifier provides 22dB of gain, +35dBm output IP3, and +24dBm of output power at 1-dB gain compression.
The new amplifier reduces the number of components required to achieve the desired output power and small signal gain, which lowers development costs and design time by enabling simpler transmit line-ups and higher integration. Based on a GaAs pHEMT design, the HMC1131 is suitable for civil and defence communications systems, including point-to-point and point-to-multi-point radios and VSAT and satellite communications applications.
The HMC1131 is capable of supplying +25 dBm of saturated output power with 16 percent PAE and is housed in a compact, leadless 4x4 mm ceramic surface-mount package.
