Programmable Attenuators
Programmable Attenuators
The PA series of programmable attenuators can attenuate input signals with high fidelity and exhibit low insertion loss, low V.S.W.R. and high isolation through the use of a special RF relay.
They can be used for a wide range of applications because of their flexible control options: manual control, wireless remote control, one-touch access of setting and selecting channels, computer control with built-in GPIB interface for automatic operation, etc..
Common specifications
Insertion loss 3.0dB Max.
Attenuation accuracy (2%+0.3)dB
Max. input power 0.25W Max.
Switching speed 20 msec
Operating temp. -10XC to +50XC

Step Attenuators
Step Attenuators
This series of attenuators is a family of push button step attenuators with 5 to 7 sections for 1 GHz and 6 sections for 2.4 GHz. By adopting fine-sensitive, durable and clicking push button switches, they form the required attenuation ratio reliably with single soft touch.
Common specifications
Max. input power 0.25W Max.
Life time 5,000Min.
Operating temp. -10XC to +50XC
