Linear Technology announced the LTC5544, a 4 GHz to 6 GHz, high dynamic range down-converting mixer.
It offers high linearity with 25,9 dBm IIP3 (input third-order intercept), high conversion gain of 7,4 dB owing to its integrated IF amplifier, and a noise figure of 11,3 dB.
These performance characteristics enable excellent dynamic range performance for both main receivers and digital pre-distortion receivers. Moreover, the IC’s RF input can withstand strong interference signals without significantly degrading its noise figure, thus preserving receiver sensitivity and enhancing robustness.
The LTC5544’s 6 GHz reach is ideally suited for wireless systems such as point-to-point broadband microwave links, 5 GHz licence-free band WiMAX radios, satellite receivers, radar systems, avionics, public safety radios and RF test systems.
The device incorporates an on-chip, high-gain IF amplifier capable of supporting IF frequencies up to 1 GHz. Also integrated are an LO buffer along with two RF balun transformers. They enable the RF and LO inputs to operate single-ended and with 50 Ω matching. The LO input requires only +2 dBm drive level.
The chip operates on a single 3,3 V supply, drawing 194 mA of current. It has a power-down feature with 0,6 μs turn-on and turn-off time, supporting Burst Mode operation or TDD (time division duplexed) systems. When disabled, the device consumes a maximum of 500 μA.
