Voltage Controlled Rf Attenuator

Voltage control phase shifter.

Voltage controlled rf attenuator.

In addition to providing low insertion loss the f2250 provides excellent linearity performance over its entire voltage control and attenuation range. 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. 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. 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.

The vva uses two analog control voltages varied between 5v and 0v to control rf signal levels over a 35 db dynamic range. Variable attenuator circuit. 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. 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.

Rf block down converter. These voltage controlled attenuators often use pin diodes and provide a variable level of attenuation dependent upon the voltage applied. The pin diode variable. Our family of voltage controlled attenuators is non reflective with ranges of 32 db of 64 db.

Digital step phase shifter. Usb ethernet control rf switch. Macom s voltage variable attenuators vvas are used in various applications for automotive and wireless markets. Tx rx module dc 70ghz rf block up converter.

Like a pin diode attenuator fet attenuators use an analogue control voltage to control the level of attenuation. 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. Rf signal generator synthesizer. Digital control step attenuator.

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. Our absorptive vvas are ideal for designs where an analog dc control signal controls rf signals levels over a 30 db amplitude range while our monolithic vvas feature low insertion loss high ip3 and wide dynamic range as well as a balance. Analog devices voltage variable attenuators vvas ensure accurate control for a wide range of applications.

The f2250 is a low insertion loss voltage variable rf attenuator vva covers a broad frequency range from 50 mhz to 6000 mhz.
