Typical Application

Description

The LTM®9013 is a 300MHz wideband, low IF receiver. Utilizing an integrated system in a package (SiP) technology, it is a μModule® (micromodule) receiver that includes a dual high speed 14-bit A/D converter, lowpass filter, differential gain stages and a quadrature demodulator.

The LTM9013 is perfect for wideband I/Q receiver applications, with AC performance that includes 59dB SNR and 1.3dB frequency flatness from DC to 300MHz. A highpass filter or simple AC coupling are used external to the device for design flexiblity. The integrated on-chip broadband transformers provide a 50Ω single-ended interface at the RF input.

A 5V supply powers the demodulator and a 3.3V supply powers the IF amplifiers for minimal distortion. A 1.8V supply allows low power ADC operation. A separate output supply allows the DDR LVDS outputs to drive 1.8V logic. An optional multiplexer allows both channels to share a digital output bus. An optional clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.
