![]() One way to accomplish this is by allowing the capacitance to be a bank of switched discrete capacitors. Because of their smaller size and higher Q, capacitors are generally chosen as the tuning element. The goal of this analysis is to determine the level of mitigation required to meet the system’s concept of operations and ensure full communications range – at minimum cost.Ĭhanging the resonant frequency of a tuned circuit can be done by varying either its inductance or capacitance. Pole/Zero offers a Cosite Analysis and Integration service to our customers to determine the level of cosite interference mitigation required for a specific communications application. For the system engineer with the challenge of enhancing a modern transceiver’s performance in a cosite environment, Pole/Zero offers our Integrated Cosite Equipment (ICE) which directly interfaces with the transceiver to provide the required cosite interference mitigation – even under fast frequency hopping applications. For the equipment designer, Pole/Zero offers multiple families of rapidly tunable notch filters, bandpass filters and pre/post-selection filters for incorporation into our customer’s equipment. Pole/Zero offers a full suite of products for these high-interference environments. ![]() The receiver must operate in the presence of large interfering signals on adjacent channels while the transmitter noise and spurious signals can artificially raise the system noise floor for collocated (cosite) receivers with the end result of system desensitization and diminished communications range. ![]() Today’s crowded communication bands and closely located receivers and transmitters operated simultaneously (SIMOP) require RF System designers to pay increasing attention to their equipment’s generation and rejection of signals and noise. ![]()
