Abstract:

The successful development of the duplexer type BL-P-017D demonstrates the feasibility of scaling a conventional balanced duplexer design to operate at 4.3 millimeters. The basic circuitry remains unchanged, while structures and assembly techniques are adapted to the reduced wavelength. The BL-P-017D balanced duplexer exceeds the performance of the BL-24 branched duplexer in terms of lower losses and lower spike and flat leakage. Mechanically the BL-P-017D duplexer is more rugged and compact because the glass reservoir and tuning mechanism are eliminated from the package. Both the 3-element and 4-element crystal protectors are marginal in high level performance, but satisfy the low level design requirements. Author
