USD025C Description

Short technical summary and product information.

The USD025C from CTS-Frequency Controls is a surface mount ceramic duplexer designed for wireless infrastructure applications. It supports a universal footprint across all FDD frequency bands, enabling the use of a common system PCB. This duplexer provides superior rejection, insertion loss, and reliability, along with excellent peak and average power handling capabilities.

Key electrical specifications include a nominal impedance of 50 ohms, an average input power of 6.0 Watt max, and a peak input power of 60 Watt max. The passband insertion loss is 3.0 dB max (5 MHz avg) for the Antenna to UL response (1850-1915 MHz) and 3.0 dB max for the DL to Antenna response (1930-1995 MHz). Return loss is 12 dB min for both paths. Attenuation levels are significant, reaching up to 63 dB min in specific bands.

Mechanically, the duplexer measures 63.0 x 11.4 x 10.6 mm and weighs 21.0 g. It is constructed from an Ag plated ceramic block with a tin plated brass shield. The operating temperature range is -40°C to +85°C.

This duplexer is suitable for high-performance carrier-grade small-cells and wide-band pico-cells requiring multi-channel or carrier aggregation.
