Diplexers/Duplexers

K&L’s WSD-00420 ESMR duplexer is reaching thresholds of this technology with it’s extreme low insertion loss and tight rejection at 861.5 MHz this filter has been optimized for performance and cost

This LC Diplexer is ideal for receiver-transmitter systems in the GSM, ISM, DCS, and PCS frequency bands. Port 1 – Port 3 operates in the 823 to 961 MHz frequency range, and Port 2 - Port 3 operates in the 1709 to 2171 MHz frequency range.

The 11DCR8C-898/943/C40-D is a very high-performance EGSM diplexer in a drop-in package. The high-Q ceramic and double cross-coupled design achieves a high level of selectivity and channel isolation while maintaining excellent passband characteristics in applications where the frequencies of the channels are very close. Measuring approximately 3.5” long by 0.33” wide by 0.641” high this mass-producible diplexer can give you an edge in your high-performance application...

Designed for testing applications, K&L Microwave’s band-pass/band-stop diplexers feature broadband matching at the common port, low insertion loss, and high isolation. These diplexers are also used in band combining/splitting applications, up/down converters, and in multiplexer modules...

K & L Microwave’s 8WZ01-62.3/58.7/U1.4-V/V is a waveguide diplexer, specifically designed to diplex two relatively narrow band widths for point-to-point transceiver. Each band pass filter is passing 1.4 GHz respectively

Narda West’s High Power PCS Band Duplexer Series provides highly selective receive/transmit combining

This ceramic duplexer operates with a 763 MHz center frequency (Rx) and a 793 MHz center frequency (Tx). It has an 8 W max input power, 50 ohm in/out impedance, a -40 °C to +85 °C operating temperature, and a 42.0 x 18.5 x 9.5 mm package size.
