Description

The UM9552 is a very long minority carrier

lifetime (70

s typical) PIN DIODE that has been

developed for low HF or LF Band Attenuator

Applications. They have been evaluated for attenuator

linearity and distortion characteristics in a Bridge Tee

Attenuator Circuit at 455 KHz (the common intermediate

frequency for AM transmitters and receivers). When the

UM9552’s are used as the two variable resistors in the

Bridged Tee Circuit, the Third Order Intermodulation

Products are below -60 dBc with 0 dBm input power

over an attenuation range of 4 dB to 30 dB.

These thicker, longer lifetime PIN diodes exhibit

a more linear forward biased resistance (R

) vs forward

bias current (If) relationship, which greatly simplifies the

design of the driver circuits that supply the bias

currents over the specified attenuation range. This task

is simplified if the low attenuation range is truncated

and the few dB are compensated by commercially

available, inexpensive 4 to 6 dB gain blocks.
