Sinclair Mobile Duplexers

  • Aug 5, 2020

MD256 SERIES Mobile duplexer, 6 cavity, N female connector, 136-174 MHz

- Compact and rugged design, ideal for mobile applications

- Low insertion loss for optimal system performance

- High isolation to minimize interference

- Tx-Rx spacing: 4.5 to 5.2 MHz; 8 to 10 MHz

     MD256 series is Sinclair's new line of mobile duplexer that features six resonators for outstanding performance. This duplexer allows bi-directional communication over a common antenna and is ideal for applications that call for a compact rugged unit, such as in vehicles, or where space is constrained.
