The HMC199AMS8 & HMC199AMS8E are low-cost general purpose dual SPDT GaAs "bypass" switches in 8-lead MSOP packages covering DC to 2.5 GHz. These four-RF-port components integrate two SPDT switches and a through line onto a single IC. The designs provide low insertion loss of less than 0.5 dB while switching passive or active external circuit components in and out of the signal path. Port to port isolations are typically 25 to 30 dB. On-chip circuitry enables positive voltage control operation at very low DC currents with control inputs compatible with CMOS and most TTL logic families. Applications include LNA or filter bypass switching and single bit attenuator switching. The HMC199AMS8E is a RoHS-compliant product.APPLICATIONSCellularISM BasestationsPCS

The HMC204 devices are passive miniature frequency doublers that are available in a monolithic microwave integrated circuit (MMIC) die (HMC204), a nonhermetic surface mount package, and an 8-lead MSOP surface mount package. Suppression of undesired fundamental and higher order harmonics range from 38 dB to 42 dB typical with respect to input signal level. The doublers utilize the same GaAs Schottky diode/balun technology found in Hittite MMIC mixers. They feature small size, no dc bias, and no measurable additive phase noise onto the multiplied signal.ApplicationsWireless local loopLocal multipoint distribution systems (LMDS)Very small aperture terminal (VSAT)Point-to-point radiosUnlicensed National Information Infrastructure (U-NII) and high performance radio LAN (HiperLAN)Test equipment

The HMC207AS8E is a miniature double- balanced mixer in an 8 lead plastic surface mount Small Outline IC (SOIC) package. This passive MMIC mixer is constructed of GaAs Schottky diodes and novel planar transformer baluns on the chip. The device can be used as an upconverter, downconverter, biphase modulator (de)modulator, or phase comparator. The consistent MMIC performance will improve system operation and assure regulatory compliance. The high LO suppression of 45 to 50 dB yields excellent carrier suppression for modulator applications.ApplicationsBase StationsCable ModemsPortable Wireless

The HMC214MS8(E) is a general purpose high dynamic range passive MMIC mixer in plastic surface mount 8 lead Mini Small Outline Package (MSOP) covering 2.4 to 4 GHz. Excellent input IP3 performance of +34 dBm for downconversion and +31 dBm for upconversion is provided for WiMax and other 3.5 GHz applications at an LO drive of +17 dBm. With a 1dB compression of +22 dBm, the RF port will accept a wide range of input signal levels. Conversion loss is 10 dB typical and LO isolations are maintained at 25 to 30 dB.This miniature single-ended monolithic GaAs FET mixer does not require any external components or bias. The DC to 1 GHz IF frequency response will satisfy many transmit and receive frequency plans configured for low side LO. The HMC214MS8(E) input IP3 performance coupled with its high P1dB rivals traditional active FET mixers while offering a much smaller 14.8mm² standard IC footprint and no DC bias.ApplicationsWiMAX, 802.16Fixed Wireless AccessWireless Local Loop

The HMC215LP4(E) is a high linearity, double-balanced converter IC that operates from 1.7 to 4.0 GHz and delivers a +25 dBm input third order intercept point. The LO amplifier output and high dynamic range mixer input are positioned so that an external LO filter can be placed in series between them. The converter provides 32 dB of LO to RF isolation and is ideal for upconverter and down converter applications.The IC operates from a single +5V supply consuming 56 mA of current and accepts a LO drive level of 2 to 6 dBm. The design requires no external baluns and supports IF frequencies between DC and 1 GHz. The HMC215LP4(E) is pin for pin compatible with the HMC552LP4(E), which operates from 1.6 to 3.0 GHz.ApplicationsPCS / 3G InfrastructureBase Stations & RepeatersWiMAX & WiBroISM & Fixed Wireless
