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”.

Important Application Notes:
- While changing RF center frequencies, RF input power must be reduced to < +20 dBm. These filters will not support “Hot RF Switching Conditions”. Please contact the factory in regards to custom features.
- Maximum strobe rate is 2kHz; Actual rate is dependent upon frequency band.

Part Number Selection Guide:
Available Options:
B. Serial Interface
C. Custom Frequency Bands (Specify START and STOP frequencies in MHz)
Interface and Control Options:
Frequency Tuning Address
Power-Pole Series filters utilize an eight-bit scheme for tune words to digitally control tuning of the center frequency. There are 250 equally spaced tuning increments across each standard filter band, resulting in 251 tune words from 00000000 to 11111010. The last 5 tune words are reserved for housekeeping functions. For further information on how to calculate tune words, please see the Frequency Tuning Address Application Note.
Interface Options
The filter comes standard with an 8-bit parallel interface, although a serial interface can be specified as an option.
DC Control Interface Characteristics
Switching Characteristics
Strobe
The filter is tuned within 15µS to the frequency designated by the tuneword existing on the eight control bit lines when the STB line is brought low. Once strobed, data existing on the tune control lines is ignored until strobed again. Maximum strobe rate is 2 kHz; Actual rate is dependent upon frequency band.
Temperature Effects
Over the –40 to +65°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.
