ADI has announced a pair of high-performance GaN PA for applications operating between 2 GHz and 6 GHz, including test and measurement, communications, Traveling Wave Tube (TWT) replacement, military/aerospace surveillance and countermeasures, and radar.
The HMC7885 is a 32-W, hermetically sealed, hybrid amplifier housed in a hermetic flange-mount package for high-reliability applications. This hybrid amplifier typically provides 21 dB of small-signal gain and 45 dBm of saturated RF-output power.
The device draws 2.2 A of quiescent current from a 28-V dc supply. Both RF input and output are DC blocked and matched to 50 ohms for ease of use. An evaluation board is available with layout and bill of materials to facilitate design-in and user application.
The HMC7748 is a fully integrated multistage Power Amplifier Module which delivers 25 W of saturated output power, accepts inputs up to −8 dBm maximum, and provides small-signal gain of 60 dB. It includes bias sequencing and regulation, and is also internally matched to 50 ohms.
This PA draws 0.7 A from a 12-V supply and up to 4 A from a 28-V supply. It includes an enable pin to provide shutdown capability so the amplifier can be turned on and off without cycling the power supplies.
