The STA5575P from SpacePath Communications is a High-Power Amplifier (HPA) that operates from 27 to 31 GHz. It delivers a peak TWT output power of 750 W and CW power of 450 W. At the HPA flange it provides a peak output power of 625 W and CW power of 370 W. It has a small signal gain of more than 70 dB. This ultra linear, high efficiency, compact amplifier is available in a lightweight, rugged, weatherproof, antenna mount enclosure with WR-28 Input/Output interfaces. It uses advanced packaging and cooling techniques to enable the unit to operate in extreme environmental conditions from direct rain to direct sunlight.
The STA5575P comes standard with RS485, RS232 and Ethernet interface options and can be remotely controlled. It uses a high-efficiency multi-collector TWT powered by an advanced power supply and provides ultra-linear performance in a compact, lightweight and rugged enclosure. The amplifier consists of a harmonic filter, receive band filter, forward power detector and reverse power detector. It has a noise power of better than -70 dBW/4kHz (Tx band) and -150 dBW/4kHz (Rx band) with a phase noise of 10 dB below IESS requirement (continuous) and harmonics of less than -60 dBc.
This TWT amplifier requires an AC supply from 100 to 240 V and consumes less than 1500 VA of power.
