The Zaxcom FDP2 is an RF filter that is used in receiver and transmitter applications. The filter is factory tuned to a frequency between 512MHz and 692MHz.When connected to a tran smitter, the filter eliminates transmitter RF noise outside the 35MHz window generated by the transmitter. The filter pushes the noise level down by an additional 50 dB allowing the transmitter antenna to be located very close to receiving antennas without the receiver desensitization that can happen without the filter.In a receiver application, the filter eliminates unwanted RF outside the bandpass of the filter that might interfere with the reception of intended wireless microphones. For example, a walkie-talkie on 460MHz might interfere with a wireless receiver operating at 520 MHz. The use of the filter should knock down the walkie signal so that it does not overload the wireless receiver. Frequency choices Zaxcom FDP2 can be ordered on any frequency within the frequency range of 512-592 MHz. The frequency ordered is the center of the filter meaning that signals 17.5 MHz above and below the center can pass through the filter. The Zaxcom FDP2 is compatible with any RF transmitter or receiver from any manufacturer to eliminate interference. Frequency block choices are as follows: Block 20: 518-542 MHz Block 21: 536-572 MHz Block 22: 560-590 MHz Block 23: 590-614 MHz Block 24 – 614-644 MHz Block 25 – 638-668 MHz Block 26 – 662-692 MHz Specifications Bandwidth 30 – 35 MHz Frequency range 512 to 692 MHz Impedance 50 ohms input/output Filter loss at center frequency 3 dB Maximum loss 50 dB Input connector SMA or SSMA Output connector SMA Show more
