High linearity active mixer

19 November 2003 Telecoms, Datacoms, Wireless, IoT Security Services & Risk Management

Linear Technology's LT5522, a high performance active downconverting mixer that operates with RF input from 600 MHz to 2,7 GHz, offers high third-order intercept (IP3) performance, extending system dynamic range and simplifying receiver design. The LT5522 RF input has an on-chip transformer that is 50 Ω matched over a wide frequency range, and both the RF input and the local oscillator ports can be driven differentially or single-ended with minimum external impedance matching components. The LO port requires low drive levels and optimum performance is achieved with an LO input power level of -5 dBm. The device draws only 56 mA of supply current at 5 V, and comes in a small footprint 4 x 4 mm plastic flat package. The LT5522's linearity makes it an excellent building block for cable headend transmitters and receivers, high performance fixed wireless access radios and satellite receivers.
