LTM9013 300MHz Wideband Receiver FeaTuresDescripTion n Integrated I/Q Demodulator, IF Amplifier, and Dual The LTM®9013 is a 300MHz wideband, low IF receiver. 14-Bit, 310Msps High Speed ADC Utilizing an integrated system in a package (SiP) technol- n External Highpass Filter Allows Bandwidth ogy, it is a μModule® (micromodule) receiver that includes Adjustment a dual high speed 14-bit A/D converter, lowpass filter, n 300MHz Lowpass Filter for Each Channel differential gain stages and a quadrature demodulator. n RF Input Frequency Range: 0.7GHz to 4GHz The LTM9013 is perfect for wideband I/Q receiver applica- n 50Ω Single-Ended RF Port tions, with AC performance that includes 59dB SNR and n 50Ω Differential LO Port 1.3dB frequency flatness from DC to 300MHz. A highpass n Frequency Flatness: 1.3dB Typical filter or simple AC coupling are used external to the device n 66dBc IM3 Level at –7dBFS for design flexiblity. The integrated on-chip broadband n 59dB SNR at –1dBFS transformers provide a 50Ω single-ended interface at n Parallel DDR LVDS Outputs the RF input. n Clock Duty Cycle Stabilizer n Low Power: 2.6W A 5V supply powers the demodulator and a 3.3V supply n Shutdown and Nap Modes powers the IF amplifiers for minimal distortion. A 1.8V n 15mm × 15mm BGA Package supply allows low power ADC operation. A separate output supply allows the DDR LVDS outputs to drive 1.8V logic. applicaTions An optional multiplexer allows both channels to share a digital output bus.
