Attenuator Relay series
INTERNAL CONSTRUCTION
DESCRIPTION
The Series A150 ultraminiature Attenuator Relays are designed for
attenuating RF signals in 50-ohm systems over a frequency range from DC

Moving Contact
to 3 GHz. Their low profile and small grid spacing makes them ideal for use
when packaging density is a prime consideration. The A150 relays eliminate
Attenuator Pad/
Contact Assembly
the need for additional external resistors.
These single section, switchable attenuator relays have internal matched thin
film attenuator pads in “L,” “T” or “Pi” configurations, as applicable. Relays are

1. Contacts will exhibit no contact chatter in excess of 10 µs or
transfer in excess of 1 µs.
2. Relays may be operated at higher frequencies with reduced RF
performance.
3. For optimal RF performance, solder case to RF ground plane.
4. Attenuation values shown are with reference to the through path
(low loss state).
5. Power handling for case temperatures of –55°C to +55°C is
1 Watt. Derate power handling 25 mW/°C above +55°C. Case
measurement point is adjacent to the relay tab.
6. Do not operate coil at maximum coil voltage continuously.
7. Insert attenuation value, see part numbering system.
8. Switching time includes bounce.
9. The slash and characters appearing after the slash are not
marked on the relay.
10. Unless otherwise specified, relays will be supplied with either
gold-plated or solder-coated leads.
