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

Bia 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.

Vcc = +5VDC, ± 10%; T= -40 to +85°C

Strobe

The filter is tuned within 15 µS 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 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 stopband 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.

4.7 Timing Requirements

4.7.1 Parallel Interface Timing

The parallel tune command interface is an 8-bit wide synchronous parallel interfae with a single-byte load. There are always 8 data bits per parallel tune. A7 is the most significant bit and A0 is the least significant bit.

MINI-POLE 16

MINI-POLE 17

4.7.2 Serial Interface Timing

The serial tune command interface is a proprietary three input and one output interface. The inputs SDI, SCLK, and STB are used for loading the tune command into the MINI-POLE while SDO shifts the last previously sent tune command out. Data is sent most significant bit (MSb) first and is clocked in on the rising edge of SCLK. After 8 subsequent SCLK rising edges, the tune command has been completely loaded into the MINI-POLE and it is ready to be enabled by the STB pin transitioning low. For best operation, it is recommended that the SCLK signal remain low while not actively loading a tune.

7.0 Tune Time

Tune times include internal processing of the tune command data and the 90% settled RF amplitude response time of the filter. This time excludes the time required to load the tune command into the filter. Low level signal measurements were utilized to show the receive tune time that can be expected at +10dBm. 

In addition, RF power in excess of +20 dBm is considered to be "hot switching" of the filter and tuning operation of the filter at these levels cannot be done reliably. It is recommended that RF is less than +20 dBm during a tune event.
