Programmable attenuators, PAH-4G/95-TTL

The programmable attenuator PAH-4G/95-TTL was developed for use in the frequency range between 50 MHz and 4000 MHz and is available up to 6000 MHz on request. This digital attenuator is suitable for applications in the telecommunications sector (e.g. GSM, DECT, UMTS, Bluetooth and all LTE frequency bands up to 4 GHz) as well as in satellite communication (L-band) and for broadcasting from FM upwards.

In addition to an absolute max. With an input power of +34 dBm, this programmable attenuator has a very good VSWR and low insertion loss with very low power consumption. The attenuation can be set very precisely and continuously from 0 – 95 dB in 0.25/0.5 dB steps without interruption.

The programmable attenuator can be used bidirectionally and does not require any additional DC protection measures on the RF paths due to internal block capacitors.

Incidentally, this low-loss attenuator has an HF-tight aluminium housing with very small dimensions.
Thanks to its control via TTL signals, the bidirectional attenuator is versatile and can therefore also be operated manually without software.
