SERIES HIGH REPEATABILITY GA152 ULTRAMINIATURE BROADBAND ATTENUATOR RELAYS SERIES RELAY TYPE DESIGNATION GA152 Attenuator relay series DESCRIPTION The Series GA152 highly repeatable ultraminiature attenuator relays are designed for attenuating RF signals in SCHEMATIC DIAGRAM 50-ohm systems over a frequency range from DC to 5 GHz. 3 5 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 2 6 resistors/attenuators. 1 7 These single section, switchable attenuator relays have an internal matched thin film attenuator pad in a Pi Terminal view. Case ground. configuration. Relays are available in a fixed increment of 20 dB. The GA152 attenuator relay features: ENVIRONMENTAL AND High repeatability. PHYSICAL SPECIFICATIONS Unique uni-frame motor design which provides high Storage 65C to +125C Temperature magnetic efficiency and mechanical rigidity. (Ambient) Operating 55C to +85C Minimum mass components and welded construction Vibration for maximum resistance to shock and vibration. 10 gs to 500 Hz (General Note 1) Advanced cleaning techniques which assures internal Shock 30 gs, cleanliness. (General Note 1) 6ms half sine Gold plated, precious metal contacts, which provide Enclosure Hermetically sealed excellent intermodulation performance. Flat amplitude vs. frequency response. Weight 0.11 oz. (3.2g) max. High isolation between control and signal path. Stable attenuation vs. temperature. Excellent phase linearity. Highly resistant to ESD.

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 .475 MAX plane. [ 12.06 ] 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.
