DESCRIPTION

(Ambient)
SERIES
The Series A152 highly repeatable ultraminiature
attenuator relays are designed for attenuating RF
signals in 50-ohm systems over a frequency range from
DC to 5 GHz. 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.

GENERAL NOTES
1. 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.
