ULTRAMINIATURE BROADBAND ATTENUATOR RELAYS SERIES DESIGNATION A150 RELAY TYPE A150 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 Stationary Contact Armature 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 SCHEMATIC DIAGRAM available in fixed increments of 1, 2, 3, 4, 5, 6, 8, 10, 16 and 20 dB, which 3 5 can used singly or in combination to achieve the attenuation levels desired. 2 6 The A150 attenuator relay features: 1 7 • Unique uni-frame motor design which provides high magnetic efficiency and mechanical rigidity. Terminal view. Case ground. • Minimum mass components and welded construction for maximum resistance to shock and vibration. • Advanced cleaning techniques which assures internal cleanliness. ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS • Gold plated, precious metal contacts, which provide excellent intermodulation performance. –65°C to +125°C Temperature Storage (Ambient) Operating –55°C to +85°C • Flat amplitude vs. frequency response.

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.
