PAH-4G/95-TTL, Programmable Attenuator
The programmable attenuator PAH-4G/95-TTL is designed for operations between 50 MHz and 4000 MHz (up to 6000 MHz on request). This digital attenuator is useable for telecom applications (e.g. GSM, DECT, UMTS, Bluetooth and all LTE frequency bands up to 4 GHz) as well as in the satellite communications (L-band) and for broadcast standards from FM.
In addition to a max. input power of +34 dBm this programmable attenuator has an excellent VSWR and low insertion loss at a low power consumption. The attenuation of this unit is adjustable continuously and without breaks from 0 to 95 dB in 0.25 / 0.5 dB steps.
The programmable attenuator can be used bidirectionally and due to the internal block capacitors no further DC voltage precautions are necessary at the RF paths.
By the way this low-loss attenuator got an RF shielded aluminium enclosure with small dimensions and is identically constructed as the attenuator PAH-8000/93-TTL.
Because of its controlling via TTL interface this bidirectional attenuator can be used very flexible and and can thereby be operated manually without software.
