The P-201G bandpass duplexer combines Sinclair's high Q
bandpass cavities into a unit of superior performance in the 132-174 MHz range.
These duplexers are easily field-tunable and feature rotatable lops for selectivity
settings other than the performance detailed below for 0.5 dB per-cavity loss. In
addition, vernier tuning is provided for fine frequency adjustments. Because of carefully
designed temperature compensation, frequency drift over the operating temperature ranges
extremely small, typically 0.5 ppm/�C.
These duplexers are available in rack-mounted or cabinet configurations.
