Revised 04/04/03
These wideband RF transformers provide excellent perfor-
mance at a very economical price. They come tapped or
untapped and are packaged in a low profile, flat top ceramic
case that makes them ideal for pick and place operations.
They feature 400 V rms isolation and 1/4 Watt RF input
power rating. Operating temperature range s -40° to +85°C.
Applications include impedance matching, voltage or
current transformation, DC isolation, balanced/unbal-
anced mixing, matching, power splitting, coupling and
signal inversion.
In addition to the standard parts shown, transformers with
other combinations of impedance ratio, insertion loss,
frequency response and current handling are available.
