SMT Temperature Variable Attenuators

                                               Attenuators are High-Reliability Chip Attenuators measuring .075”x.060”x.015” which shift attenuation in response to changes in temperature to compensate out variations in gain of an amplifier system. The                                        “PVFA SERIES” are designed as a fully passive device using a planar configuration and operate from DC-18 GHz. Because of the planar design P3 offers an variety of metalized I/O’s. Standard chips are Platinum/Silver and can  be soldered to a PC board as a flip-chip. Also offered are Gold for I/O’s for wire-bonding. All chips are RoHS compliant.

 

The                                       “W3VFA SERIES” are basically the same but with three (3) wrap-around I/O’s for PC Board mounting designed for standard solder reflow processes. These chips are designed for an operating frequency of DC-15 Ghz.

 

The                                       “VFA SERIES” are a lower frequency device operating from DC-6 GHz. which measures .145”x.122”x.020” and is an economical solution when higher frequency devices are not needed. These are offered as a low cost planar configuration and may be purchased with Platinum/Silver or Gold I/O’s (Platinum/Silver is standard).
