ADI HMC951BLP4ETR

降频器5.6GHz ~ 8.6GHz雷达

Overview

ADI’s HMC951 is a compact gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), in-phase quadrature (I/Q) downconverter that operates from 5.6 GHz to 8.6 GHz. This device provides a small signal conversion gain of 13 dB with a noise figure of 2 dB and an image rejection of 32 dBc. The HMC951A uses a low noise amplifier (LNA) followed by an image mixer that is driven by a local oscillator (LO) buffer amplifier. The image reject mixer eliminates the need for a filter following the LNA and removes thermal noise at the image frequency. The IF1 and IF2 mixer outputs are provided and an external 90° hybrid is needed to select the required sideband. The I/Q mixer topology reduces the need for filtering of unwanted sideband. The HMC951A is a smaller alternative to hybrid style, single sideband (SSB) downconverter assemblies, and it eliminates the need for wire bonding by allowing the use of surface mount manufacturing techniques.The HMC951A is available in 4 mm × 4 mm, 24-LFCSP and the HMC951BLP4ETR comes in a 24-QFN package. Both have an operating temperature range of -40°C to +85°C. Evaluation boards are available. The HMC951 is ideal for radios, radars, and electronic intelligence systems.Features: Conversion gain: 13 dB typical, Input P1dB compression: -6 dBm typical, Noise figure: 2 dB typical, LO to IF isolation: 13 dBm typical, Amplitude balance: 0.2 dB typical, RF return loss: 10 dB typical, Image rejection: 24/32 dBc typical, Input IP3: 1/3 dBm typical, 6.0 GHz to 8.6 GHz, LO to RF isolation: 48 dBm typical, RF to IF isolation: 10 dBm typical, Phase balance: -2° typical, LO return loss: 15 dB typical, IF return loss: 15 dB typical, Radio, multipoint, point to point, Radar, electronic intelligence, Military, Satellite communications, Sensors
