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 –65°C to +125°C Temperature Storage (Ambient) Operating –55°C to +85°C intermodulation performance. • Flat amplitude vs. frequency response. • High isolation between control and signal path. • Stable attenuation vs. temperature.
