PRELIMINARY Datasheet (Version 2.2) NWT190 CDMA TX Full Band BAW-filter for US PCS Features • Low-loss and high-selectivity Bulk-Acoustic-Wave Filter • Passband: CDMA Tx 1850 .. 1910 MHz • High selectivity and low temperature drift (TCF = -18 ppm/K) • Leadless Plastic Package for Surface Mounted Technology (SMT) • Thin Small Leadless Package (TSLP) • Small Package dimensions of 2.0 x 1.6mm² • Package height 0.6 mm • “Green” package, suitable for 260°C reflow temperature • Excellent ESD robustness, pyroelectric charge generation does not occur Type Marking NWT190 T190 P-TSLP-4-5 Ordering Code Package available on request TSLP-4-5 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.
