Profile: Piezo Technology, Inc. designs and manufactures a broad range of custom and standard frequency control and filter products. We are an ISO 9001:2000 certified company. Our product line includes cavity & ceramic filter, crystal resonator, microwave filter and modular sub systems. Our M9002 series SMT TCXO modular sub-system is an example of MtronPTI engineers designing a custom TCXO module for a wireless base station. Our modular sub system is featured with 500 MHz frequency, frequency vs. temperature stability of 1.0 ppm at -40°C to +85°C, and low phase noise of -140 dBc/Hz at 1 MHz. Our saw filter offers a variety of signal processing functions covering a frequency range of 20MHz to 2.5GHz. The applications can range from as small as 0.01% in fractional bandwidth for resonators, to as large as 50% for wide band filter requirements. Our saw filters are used in bandpass filters (RF and IF) for spectral shaping with image rejection, delay lines, coded waveform generation, correlators and resonators for phase noise clean up in synthesizers, along with many more examples. Our saw products consist of aluminum patterns deposited on a piezoelectric substrate that is wire bonded to a hermetically sealed package connecting it to the "outside" printed circuit boards.
