MACOM RF Amplifiers SMA1021

The SMA1021 is a discrete hybrid RF amplifier designed for a frequency range of 10 to 1000 MHz. It features a two-stage bipolar transistor feedback design that ensures consistent performance and high reliability, utilizing thin film manufacturing processes. The amplifier includes an active DC biasing network for temperature-stable operation and is available in hermetically sealed TO-8 and surface mount packages, with MIL-STD-883 environmental screening options. Key electrical specifications include a minimum small signal gain of 25 dB across the guaranteed temperature range, a maximum noise figure of 4.5 dB, and a power output of at least 14 dBm at 1 dB compression. The amplifier exhibits good gain flatness, with a maximum deviation of ±0.7 dB. Input and output VSWR values are 1.9:1 and 1.9:1, respectively, under guaranteed conditions. The device operates at a DC voltage of +5 V and has a maximum DC current of 60 mA. The SMA1021 is suitable for applications requiring reliable amplification in the specified frequency range, making it a viable option for engineers seeking a robust RF amplifier solution.
