MILPITAS, CA - August 11, 2014 - A new low power I/Q modulator from Linear Technology enables battery-powered transmitters operating in the 30MHz to 1.3GHz frequency bands, breaking new ground in power consumption, sideband suppression, carrier leakage and dynamic range performance. The LTC5599 modulator, powered from a single 2.7V to 3.6V supply, draws only 28mA current, less than 60% that of alternative solutions-with no performance sacrifice. The LTC5599 delivers outstanding native -52.6dBc sideband suppression and -51.5dBm carrier leakage without calibration. With on-chip calibration resources, performance can be further improved to -60dBc and -65dBm, respectively. Moreover the device output achieves an excellent noise floor of -156dBm/Hz with an OIP3 of 20.8dBm, delivering superior transmitter performance.
Linear Technology PR: LTC5599 92mW Direct Conversion I/Q Modulator Has Better than 50dB Sideband & Carrier Suppression
