AW-4205 Digital Attenuator

MMIC Switched Digital Attenuators & Switches, to 6 GHz

This new line of Weinschel MMIC Digital Attenuators operates over the 300 kHz to 6 GHz frequency range and is in a variety of attenuation ranges up 95 dB. These units can be controlled using either TTL or USB interfaces. Ideal for Automated Test Equipment (ATE), WiMAX, 3G/4G Fading Simulators, Engineering/Production Test Lab environments.
4248 Phase Compensated GaAs Switched Programmable Attenuator (SMA, 10-2.5 GHz)

PIN & GaAS Switched Programmables, to 6 GHz

Weinschel's Series of GaAs and Pin Switched Solid-State Programmable Attenuators are specifically designed for Wireless/Cellular, RF Simulation/Emulation, and Communication Test Application where switching speed and performance is the top priority. Other features include high IP3, higher power configurations, broadband to 6 GHz, choice of attenuation ranges, Lower power consumption, flexible dc operating voltage (+5-15 V) & Built-in TTL driver circuitry.

Mechanical Relay Switched Programmables & Phase Shifters, dc to 6 GHz

The 3200 & 3400 Series Programmable Step Attenuators are designed for use in automatic test equipment and OEM systems operating in the dc to 3 or 6 GHz frequency ranges. This series is available in many standard attenuation ranges and cell configurations as well as New Model 3456 75 ohm configuration.  Custom designed configurations are available upon request. Each cell contains a double-pole,double-throw relay that provides a zero path or attenuated path for the RF signal.

Now avaialble Model 984-1 that  provides an ajustable shift range from 0° @ DC to 630° in 10° steps @ 6 GHz (Normally linear with frequency). 

150 Series Edgline Programmable Attenuators

Edge Line (Binary) Switched Programmables, dc to 26.5 GHz

The Weinschel 150 Programmable Step Attenuators represent the widest variety of programmable attenuators available. This attenuator design is the result of an extensive development program and offers long reliable operation with exceptional accuracy and repeatability. These attenuators can provide programmable adjustments of RF signal levels in precise steps of 1 dB, 5 dB, 10 dB, or with custom steps available. Each attenuator consists of a cascaded assembly of switched attenuator cells (Figure 1). The attenuator elements located in the attenuator cell are created by a thin-film process which provides exceptional long-term stability,low power and temperature coefficients. This series uses a reed switching structure that provides rapid switching together with low insertion loss.
