MACOM RF Amplifiers SMA83-1

The SMA83-1 RF amplifier from Win Source Electronics is designed for applications requiring amplification in the frequency range of 10 to 250 MHz. It features a two-stage design that provides a typical gain of 35.5 dB, with a voltage-controlled gain adjustable from 29 dB to 39 dB depending on the supply voltage, which can range from 3 to 12 volts. The amplifier operates with a low power drain of 65 mA at 5 volts, making it efficient for various applications. This amplifier is characterized by low voltage standing wave ratio (VSWR) of less than 1.5:1 across its control range, ensuring good impedance matching. It is available in both TO-8 and surface mount packages, with hermetically sealed options for enhanced reliability. The device also includes an active DC biasing network for temperature stability, and it is suitable for use in environments that require MIL-STD-883 screening. Engineers considering this product should note its performance specifications, including a noise figure of 2.5 dB and a maximum input power of +6 dBm. The SMA83-1 is a robust choice for RF amplification needs, particularly in applications where space and power efficiency are critical.
