Richardson RFPD Inc. has annouced full design support capabilities for a GaN power amplifier from TriQuint/Qorvo. The TGA2239-CP is a 3-stage, 35W power amplifier operating from 13.4GHz to 15.5GHz. Developed on Qorvo's production 0.15µm GaN on SiC technology, the high performance amplifier offers greater than 30dB small-signal gain with 34 per cent PAE, allowing a system designer to achieve superior performance levels in a cost efficient manner, stated the company.


The device is offered in a 10-lead 15.2mm x 15.2mm x 3.5mm bolt-down package. With its high efficiency and pure-copper base assembly, the TGA2239-CP cuts the strain on system-level cooling requirements, further reducing system operating costs. Both RF ports have integrated DC blocking capacitors and are fully matched to 50Ω.

The TGA2239-CP's electrical performance and thermal management make it ideally suited for Ku-band satellite communications.

According to Qorvo, additional key features of the TGA2239-CP include: Pout: 45.5dBm at PIN = 20dBm; PAE >33.8 per cent; IM3: < -18dBc @ 38dBm Pout/Tone; and bias: VD = 22V, IDQ = 900mA, VG = -2.7V Typical.

Evaluation boards for the TGA2239-CP are available. This part is also available as a bare die.
