GENERAL DESCRIPTION
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.
