The AMMC-6345 MMIC is a broadband medium power amplifier designed for use in driving stage for transmitters that operate in various frequency bands between 20GHz and 45GHz. It can be used as a driver stage for the AMMC-6425, 6430 and 6440 (18-27GHz, 25-32GHz and 37-42GHz) 1W MMIC power amplifiers when linear operation is required. At 40GHz, it provides 24dBm of output power (P-1dB), 20dB of gain, and a 32 dBm output third order intercept (OIP3). The device has input and output matching circuitry for use in 50 environments. The AMMC-6345 integrates a temperature compensated RF power detection circuit that enables power detection of 0.8V/W at 40GHz. The device operates on 5V for current supply (negative voltage only needed for Vg). It is fabricated in a PHEMT process for exceptional power and gain performance. For improved reliability and moisture protection, the die is passivated at the active areas.
