Quadrature modulator goes direct-to-RF

Quadrature modulator is optimised for direct conversion from baseband to the 850-965MHz frequency band.

A new high performance quadrature modulator from Linear Technology is optimised for direct conversion from baseband to the 850-965MHz frequency band, providing a cost-effective solution for GSM, Edge, CDMA2000 basestations and 900MHz RFID readers The LT5558's I (in phase) and Q (quadrature phase) baseband inputs offer high impedance and a common mode voltage of 2.1V, allowing high input signal drive levels and convenient baseband coupling to active filters
