Features

In-House Designs

APITech Upconverters and Downconverters utilize in-house filter, amplifier and mixer designs which allows us to maintain critical performance alignment for exceptional amplitude and gain flatness.

Airborne Applications

APITech Upconverters and Downconverters also feature an optional dual channel frequency converter with a tunable synthesized LO, very popular in many airborne applications.
This design provides exceptional return loss through the entire band as well as suitable out of band rejection for critical military applications.

Versatile Features

Active and Passive Temperature compensation is an integral part of our designs to support rugged military environments.
Both amplitude and phase matching are critical elements of superior up/down converter performance especially in direction finding applications.

Overdrive Protection

On the DC supply side, reverse and overdrive protection plus DC Power conditioning are used to prevent and maintain adequate supply isolation.

Variable Gain Control

Using an analog or digital control voltage, these designs come with a wide variety of interfaces to support management of both gain and signal strength.

RF Input Protection

RF input protection is commonly employed using limiting circuts composed of high barrier diodes for either moderate or high power interferers.
