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.
