NOTE(S):
1) Options may be limited to particular frequency bands and/or package styles.
Consult factory for your application.
2) Filters are aligned and tested using a High Bias of +100 VDC unless otherwise
specified by the customer.
Frequency Tuning Address

MINI-POLE Series filters utilize an eight-bit scheme for tune words to digitally control tuning of the center frequency. For further information on how to calculate tune words, please see the Frequency Tuning Address Application Note.


Bias Voltage Requirement

A bias voltage is required to reverse bias the PIN diodes used to tune the filter. Very little static current (less than 1 mA) is needed. A minimum of 30 Volts is recommended for proper filter operation, although in some instances voltages as low as 12 Volts will provide acceptable performance. As this voltage is increased, the power handling capability and intermodulation are improved as shown below. A bias voltage of +100 VDC is recommended for best results, and all filters are tuned and aligned this way from the factory unless otherwise specified by the customer.
  
Interface Options

The filter comes standard with an 8-bit parallel interface, although a serial interface can be specified as an option.

Strobe

The filter is tuned within 15 µS to the frequency designated by the tuneword existing on the eight control bit lines when the line is brought low. Once strobed, data existing on the tune control lines is ignored until strobed again. Maximum strobe rate for frequencies above 10 MHz is 2 kHz, and below 10 MHz is typically 1 kHz.

RF Power Handling Capability

The filters are designed to operate with RF input power levels up to 1 Watt (+30 dBm) inband (see curves above under Bias Voltage Requirement). Signals in the filter passband up to 5 Watts at the input will not cause damage to the filter.

Temperature Effects

Over the –40 to +85°C temperature range, filters will exhibit a temperature drift of less than 80 PPM/°C, or a total of less than ±0.5% of the center frequency.
