DESCRIPTION

The Series A150 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 relays eliminate 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 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. The A150 attenuator relay features:

• 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 provide 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. Patent No. 5,315,273 INTERNAL CONSTRUCTION ArmatureStationary Contact Moving Contact Attenuator Pad/ Contact Assembly SCHEMATIC DIAGRAM Terminal view. Case ground.
