SP7T Antenna Switch Module for GSM and UMTS or CDMA Dual Mode Handset
CXM3517BER
Description
This switch is one of a range of low insertion loss, good linearity and high power MMIC antenna switch modules for GSM/UMTS or CDMA dual-mode handsets. The Sony A.S.M. contains SP7T switch, a 1.8V CMOS decoder and a dual-LPF on GSM transmit paths. The Sony GaAs junction gate pHEMT (JPHEMT) process is used for very low insertion loss and high linearity. The excellent insertion loss contributes to good sensitivity and longer talk time. www.DataSheet4U.com * A.S.M. = Antenna Switch Module (Applications: Quad Band GSM and Single Band UMTS or CDMA Dual-Mode Handset)
Features
Low insertion loss: 0.80dB (Typ.) on Tx1 (GSM Low Band Tx)
0.80dB (Typ.) on Tx2 (GSM High Band Tx) 0.33dB (Typ.) on TRx (UMTS Band I) High attenuation: 30dB (Typ.) Tx1 @ 2nd Harmonic freq. 30dB (Typ.) Tx2 @ 2nd Harmonic freq. No DC blocking capacitors (Small device footprint) Small package: VQFN-22P (2.6mm × 3.4mm × 0.8mm Typ.) Low voltage operation: VDD = +2.65V CMOS control line (CTLA/CTLB/CTLC) RX paths are changeable for band assignment Lead-free and RoHS compliant
