Product details
The CPI SA52KOA / SB52KOA is a 160W Ka-Band GaN SSPA and BUC from CPI's GaNLink Ka-Band line. It delivers up to 100W (50 dBm) of linear power at -25 dBc spectral regrowth with 8PSK in the 27.5–30.0 GHz band, and 80W (49 dBm) at -30 dBc with OQPSK in the 29.0–31.0 GHz military band.
It runs from 110–240 VAC ±10% and weighs 42 lb (19.1 kg) typ., with a WR-34 grooved waveguide flange output and Ethernet plus serial M&C (power consumption: 800 VA typ., 1200 VA max.). 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 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.
