Description:
NWT190 is a full-band PCS Tx Filter for US-CDMA and US W-CDMA that utilizes
Bulk-Acoustic-Wave Filter technology. In typical cellular phone architectures, the
transmit filter fits between the driver amplifier and the power amplifier. Benefits of this
new transmit filter are reduced insertion loss, very low temperature drift and
increased steepness of the filter skirts in lower and upper transition bands. NWT190
is packaged in a low profile plastic package.
