GA152 Attenuator relay series
DESCRIPTION
The Series GA152 highly repeatable ultraminiature
attenuator relays are designed for attenuating RF signals in

Their low profile and small grid spacing makes them ideal
for use when packaging density is a prime consideration.
The GA152 relays eliminate the need for additional external

GENERAL NOTES
1. Contacts will exhibit no contact chatter in excess of
10 s or transfer in excess of 1 s.
2. Relays may be operated at higher frequencies with
reduced RF performance.
3. For optimal RF performance, solder case to RF ground

4. Attenuation values shown are with reference to the
through path (low loss state).
5. Power handling for case temperatures of 55C to
+55C is 1 Watt. Derate power handling 25 mW/C
above +55C. 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 specifi ed, relays will be supplied with
either gold-plated or solder-coated leads.
