Triad RF introduces the 4000 Series of Bi-Directional GaN Amplifiers (BDA). The units operate in the Low and High C Bands, Federal C-1 and C-2 bands and the 5.2 & 5.8 GHz ISM bands. State-of-the-art GaN devices, along with complex matching circuits for the driver and final devices, allow the 4000 series to deliver twice the RF linear power while only consuming half to one third of the DC power of our previous generation C-Band BDAs! Various models in module or circuit card formats provide 64 QAM TX output powers of 2W, 5W, 10W, and 20W while maintaining 4.4% EVM.

The size of the 64QAM 10W unit (5.3 x 3.25 x 0.57 inches) is the same as the previous generation, but comes with several new features including the following:
– Transmit Output Power Detector
– Radio Input Power Detector
– Improved Low-Noise Amplifier (LNA), lower noise figure (NF).
– Auto detection mode provides an output signal that states whether the unit is in TX or RX.
– Improved TX and RX indicator circuitry
– Status pin indicating if the unit has exceeded acceptable temperature levels or gone into a failure mode.
– Improved base plate temperature output circuitry
– International Protection Rating = IP66
Transmit gain is 25 dB, while receive gain is 11 dB. These units still have the fastest switching time between TX and RX, less than 1 µsec! RF connectors are SMA Female and the DC connector is a 21 pin micro-Dsub.

The first 4000-Series model, the TTRM4010 has already passed environmental testing for a large defense manufacturer of high speed video and data links. Production is expected to begin Q1 of 2018.
