The HMC291SE is a general purpose broadband 2-bit positive control silicon IC digital attenuator in 6 lead SOT26 surface mount plastic package. The insertion loss is typically in between 0.4 dB - 1 dB through operating frequency range. The attenuator bit values are 4 (LSB) and 8 dB for a total attenuation of 12 dB. State error is excellent at ± 0.4 dB typical with an IIP3 of up to 57 dBm. Two bit control voltage inputs, toggled between 0V and +3V or +5V, are used to select each attenuation state at less than 25 µA each. A single VDD supply voltage of +3V to +5V applied through an external 4.7K Ohm resistor is required.ApplicationsCellularPCS, ISM, MMDSWLL handset & base station

The HMC292ALC3B is a general-purpose, double balanced, monolithic microwave integrated circuit (MMIC), mixer housed in a leadless Pb-free, RoHS compliant LCC package, that can be used as an upconverter or downconverter in the 14 GHz to 30 GHz frequency range. The HMC292ALC3B is ideally suited for applications where small size, no dc bias, and consistent IC performance are required. This mixer can operate over a wide local oscillator (LO) drive level of 9 dBm to 15 dBm. It performs equally well as a biphase modulator or demodulator. The HMC292ALC3B eliminates the need for wire bonding, allowing use of surface-mount manufacturing techniques.ApplicationsMicrowave and very small aperture terminal (VSAT) radiosTest equipmentPoint to point radiosMilitary electronic warfare (EW); electronic countermeasure (ECM); and command, control, communications and intelligence (C3I)

The HMC292A chip is a miniature, passive, gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), double balanced mixer that can be used as an upconverter or a downconverter within the 14 GHz to 32 GHz RF frequency range with a small chip area. Excellent isolations are provided by an on-chip balun that requires no external components and no dc bias. All data is measured with the chip in a 50 Ω test fixture connected via 0.076 mm (0.003 inches) ribbon bonds of minimal length <0.31 mm (<0.012 inches).ApplicationsMicrowave and very small aperture terminal (VSAT) radiosTest equipmentPoint to point radiosMilitary electronic warfare (EW); electronic countermeasure (ECM); and command, control, communications and intelligence (C3I)

The HMC304MS8(E) is a passive high IP3 mixer in 8 lead plastic surface mount Mini Small Outline Package (MSOP). This miniature single balanced MMIC mixer is constructed of GaAs Schottky diodes and novel planar transformer baluns on the chip while not requiring any external components. The RF port is balanced via the MMIC balun while the LO port is connected directly to the diodes. LO isolations are typically 20 to 30 dB. Excellent input IP3 performance of +27 to +32 dBm make the HMC304MS8(E) ideal for high dynamic range applications.ApplicationsPCS & 3G2.4 GHz ISMMMDS

The HMC305ALP4(E) is a broadband 5-bit positive control GaAs IC digital attenuator with CMOS compatible serial-to-parallel drivers packaged in leadless QFN 4x4 mm SMT package. Covering 0.7 to 3.8 GHz, the insertion loss is typically less than 1.5 to 2 dB. 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 ±0.25 dB typical with an IIP3 of up to +52 dBm. Five bit serial control words are used to select each attenuation state. A single Vcc bias of +3V to +5V applied through an external 5 kOhm resistor is required.The HMC305ALP4(E) is a replacement for the HMC305LP4(E).ApplicationsCellular/3G InfrastructureFixed Wireless, WiMax & WiBroTest Instrumentation
