The HMC598 is a x2 active broadband frequency multiplier chip utilizing GaAs PHEMT technology. When driven by a +5 dBm signal, the multiplier provides +15 dBm typical output power from 22 to 46 GHz and the Fo and 3Fo isolations are 25 dBc and 15 dBc respectively at 30 GHz. The HMC598 is ideal for use in LO multiplier chains for Point-to-Point and VSAT radios yielding reduced parts count versus traditional design approaches.APPLICATIONSClock Generation Applications:OC-768 & SDM STM-256Point-to-Point & VSAT RadiosTest InstrumentationMilitary & Space

The HMC599ST89(E) is a GaAs pHEMPT High Linearity, Low Noise Gain Block MMIC SMT amplifier covering 50 to 960 MHz. Packaged in an industry standard SOT89, the amplifi er can be used as a cascadable 75 Ohm RF or IF gain stage as well as a PA or LO driver with up to +19 dBm output power. The HMC599ST89(E) offers 14 dB of gain with a +39 dBm output IP3 at 250 MHz, and can operate directly from a +3V or +5V supply. The HMC599ST89(E) exhibits excellent gain and output power stability over temperature, while requiring a minimal number of external bias components.ApplicationsVHF / UHF AntennasHDTV ReceiversCMTS EquipmentCATV, Cable Modem & DBS

The HMC602LP4(E) Logarithmic Detector/Controller converts RF signals at its input, to a proportional DC voltage at its output. The HMC602LP4(E) employ a successive compression topology which delivers extremely high dynamic range and conversion accuracy over a wide input frequency range. As the input power is increased, successive amplifiers move into saturation one by one creating an accurate approximation of the logarithm function.The output of a series of square law detectors is summed, converted into voltage domain and buffered to drive the LOGOUT output. For detection mode, the LOGOUT pin is shorted to the VSET input, and will provide a nominal logarithmic slope of -25mV/ dB and an intercept of 18 dBm (23 dBm for ƒ ≥ 5.8 GHz). The HMC602LP4(E) can also be used in the controller mode where an external voltage is applied to the VSET pin, to create an AGC or APC feedback loop.ApplicationsCellular/PCS/3GWiMAX, WiBro, WLAN, Fixed Wireless & RadarPower Monitoring & Control CircuitryReceiver Signal Strength Indication (RSSI)Automatic Gain & Power Control

The HMC603 devices are general-purpose broadband, 5-bit positive control, GaAs, IC digital attenuators available in a 10-lead MSOP or 16-lead QSOP surface-mount (SMT) plastic package. Covering 0.7 GHz to 3.8 GHz, the insertion loss is less than 1.9 dB or 2 dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4, and 8 dB for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at ±0.15 dB typical step error with an IIP3 of +50 dBm. Five-bit control voltage inputs, toggled between 0 V and +3 V to +5 V, are used to select each attenuation state at less than 1 μA each. A single VDD bias of +3 V to + 5 V applied through an external 5 kΩ resistor is required.ApplicationsCellular/3G infrastructureISM, MMDSWLAN, WiMAX, and WiBro

The HMC606LC5 is a gallium arsenide (GaAs), indium gallium phosphide (InGaP), heterojunction bipolar transistor (HBT), monolithic microwave integrated circuit (MMIC) distributed amplifier housed in a 32-terminal, ceramic, leadless chip carrier (LCC) package that operates from 2 GHz to 18 GHz. With an input signal of 12 GHz, the amplifier provides ultralow phase noise performance of −160 dBc/Hz at a 10 kHz offset, representing a significant improvement over field effect transistor (FET)-based distributed amplifiers.The HMC606LC5 provides 13.5 dB of small signal gain, 27 dBm output IP3, and 15 dBm of output power for 1 dB compression while requiring 64 mA from a 5.0 V supply. The input and output of the HMC606LC5 amplifier are internally matched to 50 Ω and are internally dc blocked.ApplicationsRadars, electronic warfare (EW), and electronic counter measures (ECMs)Microwave radiosTest instrumentationMilitary and spaceFiber optic systems
