Attenuators
Voltage Controlled Linearized
Pulsar's voltage controlled, PIN diode linearized attenuators are available from 0.25-16.0 GHz with attenuation ranges of 32 and 64 dB. Each model includes an integrated linearizer, and a driver that controls the attenuation level. This design results in transient free switching between attenuation levels as opposed to the spurious outputs that result when an attenuation value is switched either on or off by a direct digitally controlled attenuator.

Notes:
- Transfer Function = 8 dB/Volt Typical for 32dB attenuator range.
16dB/Volt Typical for 64dB attenuator range.
Typical Switching Speed = 600 nsec
Operating Power <= 0 dBm
Power Handling = +27 dBm max.
Operating Temperature = -25°C to + 80°C
DC Supply = +12 to +15 Volts @ 100mA Typical.
-12 to -15 Volts @ 50mA Typical.
Harmonic distortion is affected by input power and frequency.
Typical distortion is 50 dBc for input power less than 0.0 dBm.
Two tone intermodulation products are typically 54 dBc for input power less than 0.0 dBm.
These attenuators are bi-directional. Either J1 or J2 can be used as input.
