The HMC283 is a GaAs MMIC Medium Power Amplifier from Hittite Microwave that covers the frequency range of 17 to 40 GHz. It has a gain of 21 dB and an output power of +21 dBm, with a power consumption of 300 mA. The chip is very small, with a size of only 1.62 mm2.

The document introduces the HMC282 chip, which is a four-stage GaAs MMIC Low Noise Amplifier (LNA) that covers the frequency range of 36 to 40 GHz. The chip can easily be integrated into Multi-Chip Modules (MCMs) due to its small size (2.30 mm2). The chip utilizes a GaAs PHEMT process offering 26 dB gain from a bias supply of +3.5V @ 90 mA with a noise figure of 3.5 dB. This LNA can be used in millimeter-wave point-to-point radios, VSAT, and other SATCOM applications.

The document describes the features and functions of the HMC280MS8G GaAs MMIC power amplifier, including output power, gain, and operating frequency range. This product is suitable for applications such as UNII, HiperLAN, and ISM.

The HMC279MS8G is a +3V GaAs MMIC driver amplifier covering the 2.5-4.2 GHz frequency range. It provides a gain of greater than 36dB and an output power of +14 dBm while operating from a single +3V supply at 60mA. No external components are required and it occupies a small area. It is ideal for applications such as 2.6-2.7 GHz MMDS, 3.5 GHz Wireless Local Loop, and 3.7-4.2 GHz Satellite (Receive and Transmit Bands).

The HMC278MS8G is a 100mW GaAs MMIC medium power amplifier covering 1.7 to 3GHz frequency range. This device is packaged in a low cost, surface mount 8 lead MSOP plastic package with an exposed base paddle for improved RF ground and thermal dissipation. The self-biased amplifier provides 21 dB of gain and +20 dBm P1dB output power while operating from a single positive supply of Vdd=+5V @ 130mA. At Vdd = +3V the gain is 19 dB with a P1dB of +16dBm. With RF I/Os matched to 50Ω, external component requirements are minimal. The MSOP8 package is ideal for low profile portable wireless devices. Use the HMC278MS8G with the HMC309MS8 integrated LNA/TxRx switch front-end for BLUETOOTH Class I, HomeRF, 802.11 WLAN, and ISM 2.4GHz radios.
