Mini-Circuits’ LDPQ-550-252+ is a miniature low temperature co-fired ceramic (LTCC) diplexer with a low pass passband of DC550 MHz and high pass passband of 1300-2500 MHz that supports a variety of applications. This model provides 0.4 dB typical insertion loss over a wide band due to its rugged monolithic construction. Housed in an 1008 ceramic form factor, it is ideal for dense signal chain PCB layouts where it complements MMIC size and performance. The LTCC fabrication process assures minimal RF performance variation while delivering a product that is well suited for environmental extremes of high humidity and temperature.
