The TSA-216051 from Teledyne Microwave Solutions is a Low Noise Block that downconverts an input frequency from 19.2 - 21.2 GHz to an output frequency from 1 - 2 GHz. It provides an output power of over 10 dBm with a selectable gain of 40, 50, or 60 dB and a noise figure of 1.6 dB. This LNB requires a DC supply voltage of 12 to 36 V and consumes up to 600 mA of current.
The unit also includes a digital attenuator and PLL lock indicator, whereas, an optional internal or external reference clock of 10, 50 MHz is available on request. This K-band LNB is available in a hermetically-sealed module that measures 5.5 x 3.5 x 1.1 inches with a WR42 waveguide interface at the input and an SMA (F) or N-type (F) connector at the output. It is ideal for airborne or SWaP applications.
