The ADG901/ADG902 are wideband switches that use a complementary metal-oxide semiconductor (CMOS) process to provide high isolation and low insertion loss to 1 GHz. The ADG901 is an absorptive (matched) switch with 50 ? terminated shunt legs, while the ADG902 is a reflective switch. These devices are designed such that the isolation is high over the dc to 1 GHz frequency range. These switches enable the user to pass dc signals up to 0.5 V without the use of a dc blocking capacitor. They have on-board CMOS control logic, thus eliminating the need for external controlling circuitry. The control inputs are both CMOS and LVTTL compatible. The low power consumption of these CMOS devices makes them ideally suited to wireless applications and general-purpose high frequency switching.Product Highlights 40 dB Off Isolation at 1 GHz 0.8 dB Insertion Loss at 1 GHz 17 dBm P1dB at 1 GHzApplications Wireless communications General purpose RF switching Dual-band applications High speed filter selection Digital transceiver front-end switch IF switching Tuner modules Antenna diversity switching list

The LTC5566 dual programmable gain downconverting mixer is ideal for diversity and MIMO receivers that require precise gain setting. Each channel incorporates an active mixer and a digital IF VGA with 15.5dB gain control range. The IF gain of each channel is programmed in 0.5dB steps through the SPI.Programmable RF input tuning via the SPI or parallel control lines makes the device attractive for wideband radio applications. Furthermore, a reduced power mode is available, programmed through the SPI.Integrated RF transformers provide single-ended 50? inputs. The differential LO input is designed for single-ended or differential drive. The differential IF output simplifies the interface to differential IF filters and amplifiers. The mixers are optimized for use up to 5GHz but may be used up to 6GHz with degraded performance.Applications 4G and 5G MIMO Receivers Diversity Receivers Distributed Antenna Systems (DAS) Network Test/Monitoring Equipment Software-Defined Radios

The LT5506 is a 40MHz to 500MHz monolithic integrated quadrature demodulator with variable gain amplifier (VGA), designed for low voltage operation. It supports standards that use a linear modulation format. The chip consists of a VGA, quadrature down-converting mixers and lowpass noise filters. The LO port consists of a divide-by-two stage and LO buffers. The IC provides all building blocks for IF down-conversion to I and Q baseband signals with a single supply voltage of 1.8V to 5.25V. The VGA gain has a linear-in- dB relationship to the control input voltage. Hard-clipping amplifiers at the mixer outputs reduce the recovery time from a signal overload condition. The lowpass filters reduce the out-of-band noise and spurious frequency components. The cut-off frequency of the noise filters is approximately 8.8MHz. The external 2xLO frequency is required to be twice the IF input frequency for the mixers. The standby mode provides reduced supply current and fast transient response into the normal operating mode when the I/Q outputs are AC-coupled to a baseband chip.Applications IEEE802.11 High Speed Wireless LAN Wireless Local Loop

The LT5528 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 con? gured as an image reject up-converting mixer, by applying 90? phase-shifted signals to the I and Q inputs. The 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 four balanced I and Q baseband input ports are intended for DC coupling from a? source with a common-mode voltage level of about 0.5V. 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 PCS and UMTS Bands Low-Noise Variable Phase-Shifter for 1.5GHz to 2.4GHz Local Oscillator Signals
