BROADBAND DISTRIBUTED AMPLIFIER
AP-0025
(POSITIVE-BIAS ONLY)
NOTE: This product is not
recommended for new designs.
Please see this letter for more
information.
The AP-0025 is a positive bias only multipurpose
amplifier available in a connectorized or surface mount EZ
package. It consists of two distributed MMIC amplifiers with
positive only bias circuitry to provide resonance free gain with
high saturated output power from 20 MHz to 25 GHz. It can
be used for generation of square wave LO drives for T3
mixers (in saturation mode), general purpose LO drive signal
generation or as a general purpose gain block for lab use (in
linear mode).
