WHITE PAPERS

Mitigating Self-Generated Communications Interference

Inadequate isolation between a transmitter and a receiver in a cosite environment results in the receiver’s diminished ability to process a weak desired signal- a condition termed “desensitization”.

The MINI-POLE^® Extended Range Series of tunable filters was developed to address applications needing a small, surface mount package with wide tunability. This tunability is accomplished by the use of multiple internal tunable filters along with high performance PIN diode RF band select switches all contained in one housing. The tunable filters are designed to minimize size and power consumption while maintaining high RF power handling and linearity characteristics. Parallel or serial digital interface can be selected by a mode pin for ease of integration into your design.

INTERFACE AND CONTROL OPTIONS:

General Information:
The MINI-ERF^® requires three supply voltages. A +5vdc analog supply, a +1.65 to +5.5vdc digital supply and a high bias voltage of +100vdc is required to bias the diodes. These supply voltages should be adequately filtered as noise present on these pins will influence the RF signal purity.

Digital Interface Information:
The digital interface format can be either SPI serial or parallel depending on the state of the mode control pin. All data input pins are CMOS/TTL compliant (VinH > 2.0vdc).
