Model GA101x Series High Power E-H Tuner
2002-2003 Gerling Applied Engineering, Inc.
Modesto, CA
EQUIPMENT DESCRIPTION
The GA101x series High Power E-H Tuners are designed for load
impedance matching in high power microwave heating systems.
Sliding plungers inside each waveguide extension are designed
with non-metallic (Teflon) contacting surfaces for reduced wear.
Reactive chokes within the plunger minimize power losses during
high power operation.
Two types of tuner design are offered. The economical
Basic
models (GA1011 thru GA1014) are operated using simple push-rod
actuators and feature clamping collars to lock the actuators in the
desired positions. The
Precision
models (GA1015 thru GA1018)
feature precision-machined plunger drive mechanisms with multi-
turn digital readout dials for accurate and repeatable positioning. In
both models, the stub housings are designed with 1/4-wave
reactive chokes allowing use in high “Q” applications.
Construction of these tuners is dip brazed aluminum waveguide,
aluminum plungers and brass/stainless steel drive mechanisms.
Models GA1014 and GA1018 feature the popular WR284 Q-D
(quick-disconnect) round flange that uses the convenient single
screw clamp (model GA8401) for waveguide connections.
