RF Micro Devices’ new RF1604 single-pole four-throw (SP4T) switch is designed for switching applications requiring very low insertion loss and high power handling capability with low DC power consumption. Its linearity performance makes it well suited for use in multimode GSM/EDGE/WCDMA and LTE applications. Performance figures include insertion loss of 0,4dB at 1GHz, 40dB isolation at 1GHz and IIP2 > 120dBm.
Very high isolation between the RF ports provides the RF separation between the transmit and receive paths which is critical in full-duplex systems. The IC also includes integrated decoding logic allowing operation from two low-voltage control lines. It is housed in a 2,5 x 2,5 mm, 12-pin, leadless QFN package.
