The GA402M802-4545R from R&K Company is a Solid-State Power Amplifier (SSPA) that operates from 4 to 8 GHz. It delivers an output power of 30 W with a small signal gain of more than 45 dB. This amplifier has spurious emissions of better than -70 dBc and harmonics of -18 dBc. It has input/output return loss of 9.5 dB and minimizes signal reflections to ensure efficient power transfer and maintenance of signal integrity. This SSPA includes protection against over temperature and power supply voltage. It is available in an enclosure that measures 430 x 560 x 177 mm with SMA-female connectors and is ideal for EMC, accelerator and telecommunication test and measurement applications. The amplifier requires an AC supply from 90 to 240 VAC and consumes 750 VA of power.
