General Description

The HMC283 chip is a four stage GaAs MMIC Medium Power Amplifi er (MPA) which covers the frequency range of 17 to 40 GHz. The chip can easily be inte grated into Multi-Chip Modules (MCMs) due to its small size. The chip utilizes a GaAs PHEMT process offering 21 dB gain and +21 dBm output power from a bias supply of +3.5V @ 300 mA. The HMC283 may be used as a frequency doubler. A B.I.T. (Built-In-Test) pad (Vdet) allows monitoring microwave output power. All data is with the chip in a 50 ohm test fi xture connected via 0.076 x 0.0127mm (3mil x 0.5mil) ribbon bonds of minimal length 0.31mm (
