PCS duplexer achieves best Tx/Rx insertion loss

Device is 40% smaller to accommodate CDMA, UMTS, modem, and femtocell applications

Constructed using the company's film bulk acoustic resonator (FBAR) technology, the ACMD-7403 PCS duplexer offers a 2.7-dB Tx insertion loss and 3.2-dB Rx band insertion loss—presented as the industry's best—to provide lowering power consumption and improved receiver sensitivity over competing solutions. The 3.0 x 3.0 x 1.2-mm duplexer is about 40% smaller than previous generation products to suit applications such as CDMA and UMTS mobile phone, data card, modem, and femtocell applications.

The device offers more than 52 dB attenuation of the transmitted signal at the receiver input and more than 44 dB rejection of transmit-generated noise in the receive band. The RoHS-compliant duplexer also achieves a power rating of 33 dBm absolute maximum Tx power. (From $2.13 ea/10,000—available now.)
