The HMC321ALP4E is a broadband nonreflective GaAs SP8T switch in low cost leadless surface mount packages. Covering DC to 8 GHz, this switch offers high isolation and low insertion loss. This switch also includes an on board binary decoder circuit which reduces the required logic control lines to three. The switch operates using a positive control voltage of 0/+5 volts, and requires a fixed bias of +5 volts. This switch is suitable for usage in 50-Ohm or 75-Ohm systems.ApplicationsThis switch is suitable for usage in DC - 8.0 GHz 50-Ohm or 75-Ohm systems:BroadbandFiber OpticsSwitched Filter BanksWireless below 8 GHz

The HMC326MS8G & HMC326MS8GE are high efficiency GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC driver amplifiers which operate between 3.0 and 4.5 GHz. The amplifier is packaged in a low cost, surface mount 8 leaded package with an exposed base for improved RF and thermal performance. The amplifier provides 21 dB of gain and +26 dBm of saturated power from a +5V supply voltage. Power down capability is available to conserve current consumption when the amplifier is not in use. Internal circuit matching was optimized to provide greater than 40% PAE.ApplicationsMicrowave RadiosBroadband Radio SystemsWireless Local Loop Driver Amplifier

The HMC329 devices are double-balanced MMIC mixers that are available in a chip (HMC329), a leadless RoHS compliant SMT package (HMC329LC3B), and an SMT leadless chip carrier package (HMC329LM3). The HMC329 devices can be used as an upconverter or downconverter. On the HMC329, the mixer is used as an upconverter or downcnverter in a small chip area of 0.85 mm × 0.55 mm. Excellent isolations are provided by on-chip baluns, and the chip requires no external components and no dc bias. Measurements for the HMC329 were made with the chip mounted and ribbon bonded into in a 50 Ω microstrip test fixture that contains 5 mil alumina substrates between the chip and K connectors. Measured data includes the parasitic effects of the assembly. RF connections to the chip were made with 0.076 mm (3 mil) ribbon bond with minimal length less than 0.31 mm (<12 mil).ApplicationsMicrowave point-to-point radiosPoint-to-point radiosPoint-to-multipoint radios and very small aperture terminal (VSAT)Local multipoint distribution systems (LMDS)Satellite communications (SATCOM)Test equipment and sensorsMilitary end useRADAR

The HMC329ALC3B is a general-purpose, double balanced mixer in a leadless, RoHS compliant, surface-mount technology (SMT) package that can be used as an upconverter or down-converter between 24 GHz and 32 GHz. This mixer is fabricated in a gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC) process and requires no external components or matching circuitry. The HMC329ALC3B provides excellent local oscillator (LO) to radio frequency (RF) and LO to intermediate frequency (IF) suppression due to optimized balun preliminary structures. The mixer operates with LO amplitude above 9 dBm. The RoHS compliant HMC329ALC3B eliminates the need for wire bonding, allowing the use of surface-mount manufacturing techniques.ApplicationsMicrowave and very small aperture terminal (VSAT) radiosTest equipmentMilitary electronic warfare (EW)Electronic countermeasure (ECM)Command, control, communications, and intelligence (C3I)
