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