Linear Technology LT5521

The LT5521 requires only –5dBm LO input power to achieve excellent distortion and noise performance, while reducing external drive circuit requirements. The LO buffer is internally 50Ω matched for wideband operation. With a 250MHz input, a 1.7GHz LO and a 1.95GHz output frequency, the mixer has a typical IIP3 of +24.2dBm, –0.5dB conversion gain and a 12.5dB noise figure.

APPLICATIONS

LT5521 Very High Linearity Active Mixer DESCRIPTIO The LT®5521 is a very high linearity mixer optimized for low distortion and low LO leakage applications. The chip includes a high speed LO buffer with single-ended input and a double-balanced active mixer. The LT5521 offers exceptional LO-RF isolation, greatly reducing the need for output filtering to meet LO suppression requirements. The device is designed to work over a supply voltage range from 3.15V to 5.25V. , LTC and LT are registered trademarks of Linear Technology Corporation.
