INRAD is now stocking a few front-end filters, which may be used in RF environments where there are many strong signals, such as locations near high power broadcast transmitters or multi-transmitter contest stations. These filters have 50 ohm input and output impedances, and are designed to go in front of a receiver. They can be transmitted through at very low levels. Incident power levels must be held below 0 dBm to prevent crystal damage. These are 6-pole crystal filters.
