LT5512EUF Datasheet

1kHz-3GHz High Signal Level Active Mixer


The LT ® 5512EUF is an active double-balanced mixer IC, op- timized for high linearity HF, VHF and UHF applications. The IC includes an integrated LO buffer amplifier to drive the mixer and an RF buffer amplifier for improved LO-RF isolation. Internal bias circuits eliminate the need for precision external resistors and allow the device to be powered-down using the enable control (EN) pin. LT5512EUF Features • Broadband RF, LO and IF Operation• High Input IP3: >20dBm from 30MHz to 900MHz +17dBm at 1900MHz• Typical Conversion Gain: 1dB• SSB Noise Figure: 11dB at 900MHz 14dB at 1900MHz• Integrated LO Buffer: Insensitive to LO Drive Level• Single-Ended or Differential LO Drive• High LO-RF Isolation• Enable Function• 4.5V to 5.25V Supply Voltage Range• 4mm ×4mm QFN Package LT5512EUF Applications • HF/VHF/UHF Mixer• Cellular/PCS/UMTS Infrastructure• High Linearity Mixer Applications• ISM Band Receivers• Wireless Medical Telemetry System (WMTS)
