Subject to Change LTM9003 12-Bit Digital Pre-Distortion Receiver Subsystem DESCRIPTION
Utilizing an integrated system in a package (SiP) tech-nology, it includes a downconverting mixer, wideband filter and analog-to-digital converter (ADC). The 12-bit ADC samples at rates up to 250Msps. Contact Linear Technology regarding customization. The high signal level downconverting active mixer is optimized for high linearity, wide dynamic range IF sampling applications. It includes a differential LO buffer amplifier driving a double-balanced mixer. Broadband, integrated transformers on the RF and LO inputs provide single ended 50Ω interfaces. The RF and LO inputs are internally matched to 50Ω from 1.1GHz to 1.8GHz. The CLK input controls converter operation and may be driven differentially or single-ended. An optional clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.
