RF & MICROWAVE SERIES A150 ULTRAMINIATURE BROADBAND ATTENUATOR RELAYS SERIES RELAY TYPE DESIGNATION 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 to 3 GHz. Their low profile and small grid spacing makes them ideal for use Armature Moving Contact 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: Unique uni-frame motor design which provides high magnetic efficiency 1 7 and mechanical rigidity. Minimum mass components and welded construction for maximum Terminal view. Case ground. resistance to shock and vibration. Advanced cleaning techniques which assures internal cleanliness. Gold plated, precious metal contacts, which provide excellent ENVIRONMENTAL AND intermodulation performance. PHYSICAL SPECIFICATIONS Flat amplitude vs. frequency response. Storage 65C to +125C Temperature (Ambient) High isolation between control and signal path. Operating 55C to +85C Stable attenuation vs. temperature. Vibration 10 gs to 500 Hz (General Note 1) Excellent phase linearity. Shock 30 gs, Highly resistant to ESD. (General Note 1) 6 msec, half-sine Enclosure Hermetically sealed Patent No. 5,315,273 Weight 0.11 oz. (3.12g) max.
