DESCRIPTION
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.
