TELEDYNE RELAYS ULTRAMINIATURE ATTENUATOR RELAY SERIES A150 DC TO 3 GHz SERIES DESIGNATION RELAY TYPE A150 ATTENUATOR RELAY SERIES INTERNAL CONSTRUCTION DESCRIPTION The A150 series ultraminiature Attenuator Relays are designed for attenuating RF signals in 50 ohm systems over a frequency range from DC to 3 GHz. Their low profile and small grid spacing makes them ideal for use when packaging density is a prime consideration. The A150 eliminate the need for additional external resistors. UPPER CONTACT MOVING CONTACT LOWER CONTACT ATTENUATOR PAD These single section, switchable attenuator relays have internal matched thin film attenuator pads in “L”, “T” or “Pi” configurations, as applicable. Relays are available in fixed increments of 1, 2, 3, 4, 5, 6, 8, 10, 16, and 20 dB which can used singly or in combination to achieve the attenuation levels desired. SCHEMATIC DIAGRAM The A150 attenuator relay features: 3 5 2 6 1 7 • Unique uni-frame motor design which provides high magnetic efficiency and mechanical rigidity. • Minimum mass components and welded construction for maximum resistance to shock and vibration. • Advanced cleaning techniques which assures internal cleanliness. • Gold plated, precious metal contacts which provides excellent intermodulation performance. • Flat amplitude vs. frequency response. • High isolation between control and signal path. • Stable attenuation vs. temperature. • Excellent phase linearity. • Highly resistant to ESD.
