Noise diodes are the fundamental building blocks for analog noise systems. They are categorized for performance characteristics that enhance their broadband noise output and flat spectral response. All Maury noise diodes can deliver symmetrical white Gaussian noise and flat output power versus frequency*.

* Flatness and output power are dependent upon peripheral circuit characteristics

Southwest Microwave’s SuperSMA is a high performance field service SMA connector. SuperSMA utilizes the basic PTFE dielectric interface (true SMA) and features low VSWR mode free through 27 GHz and less than -100 dB RF leakage. The thick outer conductor wall provides great durability to assure reliability in repeat mating, enhancing component performance. The SuperSMA interface is in accordance with MIL-STD-348.

High frequency reed relays are engineered for precision signal switching from DC up to 8 GHz, making them ideal for RF, microwave, and high-speed digital applications. These relays feature ultra-short signal paths and internal coaxial shielding with consistent 50 Ohm impedance, ensuring minimal insertion loss and excellent signal integrity. With rise times under 40 picoseconds and low contact resistance, they support fast pulse switching and high isolation in compact designs. Available in surface-mount packages with advanced shielding, they are optimized for automated test equipment, wireless systems, and high-frequency PCB layouts.
