The LBR-2195A from AVCOM is a Software-Defined Radio (SDR) Beacon Receiver that has an input frequency range in the L-Band from 950 to 2150 MHz. It has been designed with the systems integrator in mind for satellite antenna and uplink power controller system and the small form-factor makes it ideal for low-profile and restricted spaces. This receiver can search, track, and lock on BPSK-type modulated carrier signals with excellent performance and has a time-to-lock period of less than 3 s.
The LBR-2195A can handle an input power from -90 dBm to -30 dBm and has a dynamic range of 40 dB. It has a detection bandwidth from 10 to 750 kHz and a tracking bandwidth from 10 to 150 kHz. It requires a DC supply from 8 to 33 V and consumes less than 3 W of power. This SDR provides a DC output voltage that is proportional to the input RF signal over the L-band. It will remain locked on the CW carrier signal and provide the DC output voltage relative to the input RF level at the tuned center frequency.
This low SWaP-C SDR can search for carrier signals at a rate of 10 Hz and handles a delay (adjustable) of up to 5 s before locking onto any signal. It also supports analog lowpass filtering at the output and has a digital lock indicator output. This beacon receiver offers serial text-based API interface for easy implementation with simple embedded processors and uses rich set of interfaces such as USB, RS-232, and RS-422 for control. It is available in an enclosure that measures 5.50 x 4.50 x 0.94 inches with SMA input connectors and DB-25 (male) output connectors.
