Rev A

Ultra Low Profile 1608 Balun

50

to 200

Balanced

Description

The B0205F50200AHF is a low profile sub-miniature balanced to unbalanced

transformer designed for differential input locations on data conversion devices (A to

D converters). In an easy to use surface mount package covering 200 MHz to 500

MHz and superior CMRR performance, this transformer is optimized to offer

improved SFDR management during operation of the data converter device. The

B0205F50200AHF is ideal for high volume manufacturing and is higher performance

and

smaller

form

factor

than

traditional

wire

wound

transformers.

The

B0205F50200AHF has an unbalanced port impedance of 50

and a 200

balanced

port impedance. This transformation enables single ended signals to be applied to

differential ports on the data converter devices. The output ports have equal

amplitude (-3dB) with 180 degree phase differential. The B0205F50200AHF is

available on tape and reel for pick and place high volume manufacturing.
