MICRO-POLE® Tunable Band Pass Filters


Micro-Pole-Tunable-BP

Overview

The MICRO-POLE® Series of tunable filters was developed to address applications needing a small, surface mount package. This tunable filter is varactor-based in order to minimize size and power consumption. The varactor design also supports requirements up to 2 '(Z (CUSTOM DESIGNS HAVE BEEN COMPLETED). /UR STANDARD DIGITAL interface is included for ease of integration into your design and can support either serial or parallel requirements. The product includes several standard designs in various bands to support almost any application. Approximate performance is summarized in the MICRO-POLE® SERIES SELECTION GUIDE, TABLE 1, ON page 10. Evaluation card available. See page 10 for board outline drawing.

Frequency Range: 10 MHz to 1 GHz

Features & Specifications

The MICRO-POLE® is provided with the capability of shutting down the internal DC to DC converter in the event that the user wishes to decrease power consumption. The converter is controlled by the Switcher Enable (SWENA) line. Tying this line to ground inhibits the operation of the converter, and reduces the operating current of the filter. The filter will not operate in this mode, but the control logic will remain active. Returning the SWENA line to a high (or open) logic level causes the converter to start, and the filter to tune to its last commanded frequency. Retuning is not required. This input has an internal pull-up resistor and should be tied high, or left unconnected if the power-down feature is not used.
