APPLICATION NOTES The following pages contain a comprehensive collection including application information, general cosite discussion, product technical overview, and reference information.

BANDPASS FILTERS Pole/Zero's standard MICRO-POLE®, MINI-POLE®, MAXI-POLE®, and POWER-POLE® bandpass filters are 2-pole, constant Q designs and are aligned to provide a close approximation to a Butterworth response.  Filter tuning ranges are available based on popular communication bands covering 1.5MHz to 1GHz.

CONTROL DEVICES Our DR™ Controller provides a simple, easy-to-connect interface that can be combined with our broad range of Tunable RF filters for a complete turn-key filter system.

INTEGRATED COSITE EQUIPMENT Pole/Zero offers cutting-edge cosite performance in our broad product line of Integrated Cosite Equipment (ICE).  The standard product building blocks used in ICE include combinations of MICRO-POLE®, MINI-POLE®, MAXIPOLE®, POWER-POLE®, and TRAK-POLE® Filters.  ICE can be used to solve even the most demanding interference issues.

NOTCH FILTERS Notch Filters provide yet another tool to address cosite interference issues.  Our standard notch designs utilize similar architectures as the MINI-POLE®, MAXIPOLE®, and POWER-POLE® bandpass filters in order to take advantage of economies of scale and control costs.

PRESELECTORS Our preselector products combine several filter bands in a single, economical package in order to address applications requiring broad frequency coverage (1.5 MHz to 3 GHz).  Preselector designs are optimized for size, weight, and power (SWAP) for even the most demanding applications.  All of the preselector products are now incorporated into Pole/Zero’s ICE1000 Series product family.
