The SSM3302 is a fully integrated, high efficiency, stereo Class-D audio amplifier. The application circuit requires minimal externalcomponents and operates from a single 7 V to 18 V supply. The device is capable of delivering 2 ? 10 W of continuous output power into a 4 ? load (or 2 ? 8 W into 8 ?) with 98 dB. Spread spectrum pulse density modulation (PDM) is used toprovide lower EMI radiated emissions compared with other Class-D architectures. The SSM3302 includes an optional modulation select pin (ultralow EMI emission mode) that significantly reduces the radiated emissions at the Class-D outputs, particularly above 100 MHz. The SSM3302 can pass FCC Class-B emissions testing with an unshielded 20 inch cable using common-mode choke-based filtering.The fully differential input of the SSM3302 provides excellent rejection of common-mode noise on the input. The device also includes a highly flexible gain select pin that only requires one series resistor to choose a gain between 9 dB and 24 dB, with no change to the input impedance. The benefit of this is to improve gain matching between multiple SSM3302 devices within a single application compared with using external resistors to set gain.The SSM3302 includes an integrated voltage regulator thatgenerates a 5 V rail.The SSM3302 has a micropower shutdown mode with a typical shutdown current of 10 ?A. Shutdown is enabled by applying a logic low to the SD pin. The device also includes pop-and-click suppression circuitry that minimizes voltage glitches at the output during turn on and turn off, reducing audible noise during activation and deactivation.Other included features to simplify system level integration of the SSM3302 are input low-pass filtering to suppress out-ofband DAC noise interference to the pulse density modulator, fixed input impedance to simplify component selection across multiple platform production builds, and a thermal warning indicator pin.The SSM3302 is specified over the commercial temperaturerange (?40?C to +85?C). It has built-in thermal shutdown andoutput short-circuit protection. It is available in a halide-free,40-lead, 6 mm ? 6 mm lead frame chip scale package (LFCSP).APPLICATIONS Mobile computing Flat panel televisions Media docking stations Portable electronics Sound bars

The HMC1113LP5E is a compact GaAs MMIC I/Q downconverter in a leadless 5 x 5 mm low stress injection molded plastic surface mount package. This device provides a small signal conversion gain of 12 dB with a noise figure of 1.8 dB and 25 dBc of image rejection. The HMC1113LP5E utilizes an LNA followed by an image reject mixer which is driven by an LO buffer amplifier. The image reject mixer eliminates the need for a filter following the LNA, and removes thermal noise at the image frequency. I/Q mixer outputs are provided and an external 90? hybrid is needed to select the required sideband. The HMC1113LP5E is a much smaller alternative to hybrid style image reject mixer downconverter assemblies, and it eliminates the need for wire bonding by allowing the use of surface mount manufacturing techniques.Applications Point-to-Point &?Point-to-Multi-Point Radio Military Radar, EW & ELINT Satellite Communications Maritime & Mobile Radios
