SERIES HIGH REPEATABILITY A152 ULTRAMINIATURE BROADBAND ATTENUATOR RELAYS SERIES RELAY TYPE DESIGNATION A152 Attenuator relay series INTERNAL CONSTRUCTION DESCRIPTION The Series A152 highly repeatable ultraminiature attenuator relays are designed for attenuating RF signals in 50-ohm systems over a frequency range from Stationary Contact Armature Moving Contact DC to 5 GHz. Their low profile and small grid spacing Attenuator Pad/ makes them ideal for use when packaging density is Contact Assembly a prime consideration. The A152 relays eliminate the need for additional external resistors/attenuators. These single section, switchable attenuator relays have an internal matched thin film attenuator pad in a Pi SCHEMATIC DIAGRAM configuration. Relays are available in a fixed increment of 20 dB. 3 5 The A152 attenuator relay features: 2 6 High repeatability. 1 7 Unique uni-frame motor design which provides high magnetic efficiency and mechanical rigidity. Minimum mass components and welded construction Terminal view. Case ground. for maximum resistance to shock and vibration. Advanced cleaning techniques which assures internal ENVIRONMENTAL AND cleanliness. PHYSICAL SPECIFICATIONS Gold plated, precious metal contacts, which provide Storage 65C to +125C Temperature excellent intermodulation performance. (Ambient) Operating 55C to +85C Flat amplitude vs. frequency response. High isolation between control and signal path. Vibration 10 gs to 500 Hz (General Note 1) Stable attenuation vs. temperature. Excellent phase linearity. Shock 30 gs, (General Note 1) 6ms half sine Highly resistant to ESD. Enclosure Hermetically sealed Patent No. 5,315,273 Weight 0.11 oz.
