The ADMFM2000 is a dual-channel microwave downconverter, with input RF and local oscillator (LO) frequency ranges covering 5 GHz to 32 GHz, with an output intermediate frequency (IF) frequency range from 0.5 GHz to 8 GHz. The downconverting mixer can also be bypassed allowing direct access to the 0.5 to 8 GHz IF path. A common LO input signal is split to feed two separate buffer amplifiers to drive the mixer in each channel. Each down conversion path consists of a low noise amplifier (LNA), a mixer, an IF filter, a digital step attenuator (DSA), and an IF amplifier.
Fabricated using a combination of surface mount and bare die components, the ADMFM2000 provides precise gain adjustment capabilities with low distortion performance. The ADMFM2000 comes in a compact, shielded 20.00 mm × 14.00 mm, 179-ball chip scale package ball grid array (CSP_BGA) and operates over a temperature range of −40°C to +85°C.
