Broadband Preamplifier for up to 7 GHz
Luckily the times when DIY projects in the GHz range have been the final frontier that’s rarely been crossed are over. Monolithic Microwave Integrated Circuits (short MMIC) are making the design of microwave (pre-)amplifiers a piece of cake. Mini-Circuits GVA-84+ is a perfect candidate for a simple 7 GHz preamplifier. The datasheet [1] of the […]
