Voltage Controlled Rf Attenuator

Rf block down converter.

Voltage controlled rf attenuator.

They operate with a control voltage of 0 to 8 vdc and handle 27 dbm maximum input power. The f2250 is a low insertion loss voltage variable rf attenuator vva covers a broad frequency range from 50 mhz to 6000 mhz. Qorvo s cmd285c3 is dc to 20 ghz gaas mmic absorptive voltage variable attenuator vva housed in a leadless surface mount package ideally suited for military space and communications systems. Usb ethernet control rf switch.

In any rf system there is a need for a constant impedance and this design provides an acceptable match to 50ω over a wide range of attenuation levels. Analog devices voltage variable attenuators vvas ensure accurate control for a wide range of applications. Over 400 coaxial surface mount and mmic attenuator models for 50 ohm 75 ohm system including fixed attenuators high power attenuators digital step programmable attenuators voltage variable attenuators and more. Digital control step attenuator.

Our vvas operate from 10 mhz to 45 ghz and are ideal for cellular infrastructure handset gain control radar systems satellite radios and test equipment. Our family of voltage controlled attenuators is non reflective with ranges of 32 db of 64 db. These are only broad categories for rf attenuators they can be categories in a variety of ways according to the application and the type of attenuator technology that is used. Like a pin diode attenuator fet attenuators use an analogue control voltage to control the level of attenuation.

The vva uses two analog control voltages varied between 5v and 0v to control rf signal levels over a 35 db dynamic range. Analog voltage variable attenuators. Voltage control phase shifter. These vva s have nearly half the insertion loss of competitive solutions high ip3 performance and are linear in db attenuation across the voltage control range.

Tx rx module dc 70ghz rf block up converter. Dc passing and dc blocking models. In addition to providing low insertion loss the f2250 provides excellent linearity performance over its entire voltage control and attenuation range. Variable attenuator circuit.

Pin diodes are used and the frequency range is 0 25 16 ghz. Alternatively the renesas voltage variable attenuators vva offer customers analog control for applications that require more precise attenuation. These voltage controlled attenuators often use pin diodes and provide a variable level of attenuation dependent upon the voltage applied. The pin diode variable.
