The DSC-R212 is a linear AGC balanced receiver ideally suited for a variety of optical detection applications up to optical wavelengths of 2.2µm. This receiver offers a variety of user-adjustable characteristics such as RF gain, bandwidth and frequency response, output amplitude and mode of operation (AGC or manual gain control). The DSC-R212 also offers RF bandwidth to 18GHz, gain to 5600 V/W and low power dissipation. The DSC-R212 is available in GPPO packaged module with differential RF outputs, as well as in Discovery¹s Lab Buddy instrument.
