The LT5518 is a direct I/Q modulator designed for high performance wireless applications, including wireless infrastructure. It allows direct modulation of an RF signal using differential baseband I and Q signals. It supports PHS, GSM, EDGE, TD-SCDMA, CDMA, CDMA2000, W-CDMA and other systems. It may also be configured as an image reject up-converting mixer, by applying 90? phase-shifted signals to the I and Q inputs. The high impedance I/Q baseband inputs consist of voltage-to-current converters that in turn drive double-balanced mixers. The outputs of these mixers are summed and applied to an on-chip RF transformer, which converts the differential mixer signals to a 50? single-ended output. The balanced I and Q baseband input ports are intended for DC coupling from a source with a common mode voltage level of about 2.1V. The LO path consists of an LO buffer with single-ended input, and precision quadrature generators that produce the LO drive for the mixers. The supply voltage range is 4.5V to 5.25V.Applications Infrastructure Tx for DCS, PCS and UMTS Bands Image Reject Up-Converters for DCS, PCS and UMTS Bands Low Noise Variable Phase-Shifter for 1.5GHz to 2.4GHz Local Oscillator Signals

The SSM2377 is a fully integrated, high efficiency, Class-D audioamplifier. It is designed to maximize performance for mobilephone applications. The application circuit requires a minimumof external components and operates from a single 2.5 V to 5.5 Vsupply. It is capable of delivering 2.5 W of continuous output powerwith 100 dB.Spread-spectrum pulse density modulation (PDM) is used toprovide lower EMI-radiated emissions compared with otherClass-D architectures. The inherent randomized nature ofspread-spectrum PDM eliminates the clock intermodulation(beating effect) of several amplifiers in close proximity.The SSM2377 produces ultralow EMI emissions that significantlyreduce the radiated emissions at the Class-D outputs,particularly above 100 MHz. The SSM2377 passes FCC Class Bradiated emission testing with 50 cm, unshielded speaker cablewithout any external filtering. The ultralow EMI emissions of theSSM2377 are also helpful for antenna and RF sensitivity problems.The device is configured for either a 6 dB or a 12 dB gain settingby connecting the GAIN pin to the VDD pin or the GND pin,respectively. Input impedance is a fixed value of 80 k?, independentof the gain select operation.The SSM2377 has a micropower shutdown mode with a typicalshutdown current of 100 nA.
