| 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..

| 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. |
