Flange Mounted Double-Balanced
Biasable Mixers
Description
Part Number DMB1-12A is a two-port mixer utilizing
bridge diode quad. RF and IF are diplexed into the same
port via an internal diplexer. At crossover frequency
(RF = IF), response for each is down 3 dB. Self-adjusting
biasing automatically reduces dc bias level as the LO
power is increased. Available with options such as
built-in PIN limiter on the RF port. Contact factory.
Part Number DMB2-18A is a one-port design utilizing a
bridge quad of Schottky diodes. RF and IF are directed
into separate ports via an internal diplexer. The LO port
uses a self-adjusting biasing circuit which automatically
decreases the dc voltage as the LO power is increased.
