It features an on-chip reference attenuator for use with a n e x t e r n a l o p - a m p t o p r o v i d e s i m p l e s i n g l e v o l t a g e attenuation control, 0 to -3V. The device is ideal in designs where an analog DC control signal must cont r o l R F s i g n a l l e v e l s over a 30 dB amplitude range. Applications include AGC circuits and temperature compensation of multiple gain stages in microwave point-to-point and VSAT radios. in ar Functional Diagram Pr el im ATTENUATORS - SMT 1 GaAs MMIC SMT VOLTAGE-VARIABLE ATTENUATOR, DC - 8 GHz Electrical Specifi cations, TA = +25° C, 50 ohm system Parameter Typical Max Units 1.5 2.5 dB DC - 8 GHz Attenuation Range DC - 8 GHz 27 32 dB Return Loss DC - 8 GHz 5 10 dB tRISE, tFALL (10/90% RF) tON, tOFF (50% CTL to 10/90% RF) 2 8 ns ns Input Power for 0.25 dB Compression (0.5 - 8 GHz) Min.
