Switchplexers use LTCC technology

22 May 2002 Telecoms, Datacoms, Wireless, IoT

Murata has previously described a Low Temperature Cofired Ceramic (LTCC) dual-frequency switchplexer, a design that integrates diode switches, low pass filters and matching circuits into one package. This device is actually one of a range of dual frequency switchplexers. The company says that just about all compatible band combinations are available, including GSM/DCS, DCS/PCS, Bluetooth, AMPS etc.

Terminals that support GPRS and the like are still under pressure to get smaller, in particular with good performance in smaller packages. Murata responds to this demand by continuously evolving its switchplexers. As an example, the surface mounting LMC33 has a maximum height of 1,8 mm on a nominal footprint of 5,4 x 4,0 mm, giving a reduction of 36% by area and 42% by volume over other versions. At the same time electrical characteristics like bandwidth, insertion loss, VSWR, Tx/Rx isolation and power consumption are superior.
