Product details
The CPI SA46KOA / SB46KOA is a 40W Ka-Band GaN SSPA and BUC from CPI's GaNLink Ka-Band line. It delivers 25W (44 dBm) of linear power with 8PSK, OQPSK or QPSK carriers at -30 dBc spectral regrowth, and 20W two-tone per MIL-STD-188-164B at 30–31 GHz, using CPI's MCC technology.
It runs from 37–59 VDC (48 VDC nominal); AC/DC converter available and weighs 9.1 lb (4.1 kg) SSPA, 10 lb (4.6 kg) BUC, max., with a WR-28 grooved waveguide flange (WR-34G option) output and Ethernet plus serial M&C (power consumption: 250 VA max. (SSPA) / 260 VA max. (BUC) at 25W out; 25 VA in standby). Choose the SA model for a Ka-band input or the SB model, which adds an integrated block upconverter for an L-band (950–1950 MHz, 1250–3750 MHz or 1000–2000 MHz) input.
Specify SA (SSPA) or SB (BUC) and the output band when ordering; Digisat confirms the full configuration with CPI. The GaNLink Ka-Band Series comes in 3 listed models; compare them on the series page.
