QuinStar Technology’s QSS and QSD series millimeter-wave broadband PIN switches cover the frequency range of 18 to 110 GHz in seven waveguide bands. These waveguide switches are constructed with a rugged, split block mechanical design that utilizes PIN diodes. Most standard switches operate over a full waveguide band, and all can be optimized over a specific narrower frequency range for better isolation or lower insertion loss. They are ideal for signal attenuation, on/off switching such as receiver protection, and variable pulse width control. The switches can handle RF power levels of up to 27 dBm (0.5 Watt) and optional integral drivers that accept a TTL input as the control signal are available.
Series QSS/QSD switches are useful for signal switching, receiver protection, pulse modulation and test equipment applications.
