Abstract :
The authors discuss the design and the performance of a two-tier monolithic matrix amplifier. The amplifier utilizes eight MESFETs evenly distributed over two tiers. A gain of 15.5+or-0.9 dB at a worst return loss of -12 dB, a maximum noise figure of 7 dB, and a minimum output power of P/sub 1dB/=15.5 dBm were obtained in the two-tier module across the 2-18-GHz frequency band. A brief description of the circuit design and its fabrication is presented. The unit´s environmental behavior over the temperature range of -55 degrees C to +95 degrees C is also described.<>
