Their low profile and small grid spacing makes them ideal for use when packaging density is 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” configuration. Relays are available in a fixed increment of 20 dB. The A152 attenuator relay features: • High repeatability. • 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.

Contacts will exhibit no contact chatter in excess of 10 µs or transfer in excess of 1 µs. 2. Relays may be operated at higher frequencies with reduced RF performance. 3. For optimal RF performance, solder case to RF ground plane. 4. Attenuation values shown are with reference to the through path (low loss state). 5. Power handling for case temperatures of –55°C to +55°C is 1 Watt. Derate power handling 25 mW/°C above +55°C. Case measurement point is adjacent to the relay tab. 6. Do not operate coil at maximum coil voltage continuously. 7.Insert attenuation value, see part numbering system. 8. Switching time includes bounce. 9. The slash and characters appearing after the slash are not marked on the relay. 10.Unless otherwise specified, relays will be supplied with either gold-plated or solder-coated leads.
