Diplexers/Duplexers

PRODUCTS AND SERVICES

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.

The electronics industry is truly dynamic. Digi-Key represents one of the fastest-growing electronic component distributors within that marketplace. The company's remarkable sales growth and its ability to consistently out perform the industry is the best evidence of Digi-Key's superior service.
The ACMD-7409 is an environmentally green version of the ACMD-7402 duplexer and is a miniature duplexer designed for US PCS handsets.
Multilayer Diplexer (DPX205950DT-9008A1)by Digi-Key.

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.

This cavity diplexer features a compact size, a ruggedized package for Hi-Rel environments, high isolation and small separation between channels, and more. It operates in the 400-500 MHz frequency range and is ideal for airborne, ship, or vehicle mount applications in military environments.

This diplexer uses TE Mode waveguide puck resonators to achieve narrowband filters of less than 0.25% bandwidth yet still provide a pass band loss on the order of < 1.5 dB. In addition to the low loss provided by the high Q ceramic resonators, cross coupling is used to achieve very deep rejection of 75 dBc at a 4:1 shape factor. This device also incorporates a sampling coupler and is available in both diplexer and double band pass configurations in frequency ranges of 2250 MHz to 2800 MHz...
