Attenuators

There is one aspect of high frequency amplifiers with GaAs semiconductors that makes life difficult: their gain reduces with rising temperatures. Complex feedback circuits are normally necessary in order to compensate for this effect. Japanese manufacturer Susumu offers an elegant solution that is both simple and inexpensive: the thermo-variable attenuators in the product families, PXV1220S, PBV1632S and PAV3137S save space and reduce complexity. The chip attenuators contain a network of resistors with a temperature-variable attenuator, the characteristics of which compensate for the temperature drift of the GaAs component.

Field Replaceable Connectors

Pasternack’s new field replaceable RF connectors include SMA, 3.5 mm, 2.92 mm, 2.4 mm and 1.85 mm types with two-hole and four-hole mounting configurations. Each connector utilizes a metal ring that grounds or mates with the component ground and will work with a range of different pin sizes. These types of connectors can be used on various sealed RF components as replaceable RF interconnects where the component has a pin exposed. The connector is attached to the wall of the component with screws and accepts the interface pin.
