The HMC346LP3 is an absorptive voltage variable attenuator (VVA) from Hittite Corporation. It operates from DC to 14 GHz and has a 30 dB attenuation range. It features a low phase shift, simplified voltage control, and a small package. It is ideal for basestation infrastructure, fiber optics and broadband telecom, microwave radio and VSAT, military radios, radar, and ECM, and test instrumentation.

The HMC346LC3B is a 30dB absorptive Voltage Variable Attenuator (VVA) from Hittite Corporation. It operates from DC to 18GHz and is packaged in a 3 x 3mm SMT package. The device features an on-chip reference attenuator for use with an external op-amp to provide simple single voltage attenuation control, 0 to -3V. It is ideal for designs where an analog DC control signal must control RF signal levels over a 30dB amplitude range.

HMC346G8 is an absorptive Voltage Variable Attenuator (VVA) from Hittite Microwave, operating from DC to 8 GHz. It features an on-chip reference attenuator for use with an external op-amp to provide simple single voltage attenuation control, 0 to -3V. The device is ideal in designs where an analog DC control signal must control RF signal levels over a 30 dB amplitude range.

The HMC346C8 is an absorptive Voltage Variable Attenuator (VVA) from Hittite Microwave that operates from DC - 8 GHz and has a 30 dB attenuation range. It is ideal for basestation infrastructure, fiber optics & broadband telecom, microwave radio & VSAT, military radios, radar, & ECM, and test instrumentation applications.

The HMC346 is a wideband voltage variable attenuator from Hittite Corporation, operating from DC-20GHz with a 32dB attenuation range.

The HMC341 is a GaAs MMIC Low Noise Amplifier (LNA) from Hittite Corporation. It covers the frequency range of 24 to 30 GHz and has a gain of 13 dB and a noise figure of 2.5 dB.

The document describes the features and characteristics of the HMC342 GaAs MMIC low noise amplifier, including frequency range, gain, noise figure, etc.

The HMC344 is a broadband non-reflective GaAs MESFET SP4T switch chip from Hittite. Covering DC to 8.0GHz, this switch offers high isolation and low insertion loss and extends the frequency coverage of Hittite's SP4T switch product line. This switch also includes an on board binary decoder circuit which reduces the required logic control lines to two. The switch operates using a negative control voltage of 0/-5V, and requires a fixed bias of -5V. All data is tested with the chip in a 50 Ohm test fixture connected via 0.025 mm (1 mil) diameter wire bonds of minimal length.

The HMC344LP3 is a broadband non-reflective GaAs MMIC SP4T switch from Hittite Corporation. It features a wide frequency range (DC-8GHz), low insertion loss and high isolation, and is suitable for applications such as fiber optics, switched filter banks and wireless.

This document describes the features and characteristics of the HMC345LP3 microwave switch, including broadband performance, high isolation, and low insertion loss. The switch is suitable for DC - 8.0 GHz 50-Ohm or 75-Ohm systems and can be used in broadband, fiber optics, switched filter banks, and wireless applications below 8 GHz.

HMC339 is a GaAs MMIC SUB-HARMONICALLY PUMPED MIXER from Hittite Microwave Corporation. It works in the frequency range of 33 - 42 GHz and has an integrated LO amplifier. It can be used as an upconverter or downconverter. This chip uses GaAs PHEMT technology, which results in a small overall chip area of 1.07mm2. The 2LO to RF isolation is excellent, eliminating the need for additional filtering.

This document describes the features and characteristics of the HMC338 GaAs MMIC SUB-HARMONICALLY PUMPED MIXER, including the integrated LO amplifier, high 2LO/RF isolation, and small size.

HMC331 is a passive frequency doubler produced by Hittite Microwave Corporation. It is suitable for wireless local loop, LMDS, VSAT and point-to-point radio equipment.

The HMC330 is a broadband double balanced sub-harmonically pumped passive mixer that may be used as an upconverter or downconverter. The mixer requires no external matching or bias. This design was optimized to provide better 1dB compression performance as compared to the HMC266 under the same LO drive levels. The HMC330 provides greater than 38 dB LO to RF and 2LO to RF isolation performance.
