Amphenol type 323-11506-3 These are BRAND NEW, (original bags) Amphenol type 323-11506-3, SP4T RF relays. 50 ohms impedance, with four 26 vdc coils. Connectors are BNC female. Consists of a common and 4 ports. When not energized, the ports are grounded. This configuration allows the common to be connected to any or all of the 4 ports at the same time, depending on how many coils are energized. Dimensions: 2" wide X 3" long by 1.75" High. With 4 holes for easy mounting. Always satisfaction guaranteed. NOTE: We also frequently have the same Amphenol relay shown above, as well as equivalent types (such as FXR #323-011651-3, Arrowsmith # 323-11506-14,  or Dow-Key # 243-6302-1) in used / checked condition, for $49 each.  Inquire as to availability.

Single pole, double throw (SPDT) RF

We have a large quantity of these single pole, double throw (SPDT) RF coaxial relays for sale . These are mil-spec types, removed from military equipment. They are by several manufacturers, including DowKey, Motorola, and Amphenol. Coil voltage is 26 volts DC. Maximum power is 150 watts. Maximum usable frequency exceeds 4 Ghz. Gold plated contacts, silver-plated body, and Teflon dielectric. Connectors are BNC female. Isolation is 50 dB at 50 Mhz and 30 dB at 4 Ghz.

Note: These relays ground the position not selected . The common input is never grounded, of course. This is an excellent voltage surge protection feature in many antenna switching applications.

Automated Measurements Corporation model 42-24

We have a few of these relays by Automated Measurements Corporation, model 42-24. They also have a tag that says: Modified unit, model 42024-3. We have been told that these are reed relays, which would be extremely fast, but very low power level applications. They switch in a few hundred microseconds. They were used to carry pulse generator waveform and trigger data to a data analyzer used in testing semiconductors and complex systems that used a risetime storage device similar to the Tektronix sampling scopes. They should be good for about 5 watts RF at 144 Mhz. We have no other data on these whatsoever. The configuration appears to be SP4T, with BNC connectors. Control cable connector is a 15 pin "D" connector. (We should have these available on request.) Excellent condition. Military surplus, removed from equipment.
