R&K SD Series

R&K’s SD series products are semi-custom RF phase sensitive detectors that output two orthogonal detection voltages proportional to the mutual phase and voltage difference from the RF input and the LO input to be referenced. A super high level double balanced mixer is used internally, and a buffer circuit with operational amplifiers is used for the two detection outputs (Sine and Cosine), resulting in an extremely wide dynamic range.

Model name and the values listed in the table are some examples of previously manufactured products. Input center frequency, passband width, and output frequency pathwidth can be customized based on the customer’s requirement salon as they are within our technical capability.

As our standard specification, the input frequency of 10MHz to 1000MHz and output frequency bandwidth of DC to 50MHz can be covered. If input frequency bandwidth is not specified, it will be 10% of the center frequency.
