A152 Attenuator relay series
INTERNAL CONSTRUCTION DESCRIPTION
The Series A152 highly repeatable ultraminiature
attenuator relays are designed for attenuating RF
signals in 50-ohm systems over a frequency range from

need for additional external resistors/attenuators.
These single section, switchable attenuator relays have
an internal matched thin film attenuator pad in a Pi
