Wed, 09/11/2002 - 5:17am
Model RKa-LNA is a low noise receiver covering the 26.5 to 40 GHz frequency band. A phase locked oscillator (internal or external reference) is tripled to provide the high side LO input. The desired LO frequency is filtered of all unwanted harmonics. The IF frequency is 2 - 15.5 GHz. The RF chain consists of an LNA, full band isolator and low pass filter which rejects the LO and upper sideband frequencies by >50 dB. Typical noise figure is 3.5 dB with 4.5 dB maximum. RF to IF gain is 14 dB (typical) and input bias is +12 V @ 0.5 amp. www.spaceklabs.com; (805) 564-4404
