TF0113 Digitally Tunable LC Filter Datasheet

TF0113 Series Digitally Tunable LC Filters

4. Passband Variation (FSIG ±1.5%, peak-valley): < 1.5dB
5. FTUNE VSWR (within the FSIG Passband into 50Ω): < 2.0:1
6. Absolute Stop Band Attenuation:
FSIG ±10%: 16 dB minimum
2x FSIG to < 750MHz: 35dB minimum
FSIG ±20%: 27 dB minimum
750MHz to 1.2GHz: 25dB minimum
30MHz to ½ FSIG: 38dB minimum
1.2GHz to 2.0GHz: 15dB minimum
rd
7. In-band 3 Order Intercept: +40dBm minimum
2 tones at FTUNE ±0.5%, +24dBm/tone
8. In Band RF Power Handling: ≤ 2.0-watts CW
9. Out of Band Power Handling: 5-watts CW, > FTUNE ±10%
10. ZIN/ZOUT: 50Ω nominal
11. Tuning Method:
Digital Control: 500-steps (501 frequencies), 8-bit parallel control
Band-0, 90.54MHz to 225MHz: FSTEP = 0.54MHz
Band-1, 226.148MHz to 512MHz, FSTEP = 1.148MHz
Tuning Speed (+10dBm reference): < 20µsec
Tuning Speed is defined from second rising edge of STROBE to 90% steady state RF voltage.
12. DC Power:
VCCA: +5VDC ±10%
ICCA: < 320mA
VCCD: +3.3VDC ±10%
ICCD: < 30µA
Vbb: +200VDC ±10%
Ibb: < 5mA
Note 1:
FSIG = Frequency of the signal,
FCOM is the target command frequency that the filter will be directed to.
FCOM = Integer ((FSIG- FMIN)/ FSTEP)* FSTEP + FMIN
Note 2:
Vbb= +200V, the filter command frequencies are set up with +200V applied.
Vbb = +100V (Ibb = 5mA), Power handling reduces to 1.25-watt.

IV. Interface Timing: (cont.)
When the STROBE goes HIGH, it activates the tuning process and the BAND BYTE would be stable and read available for
approximately 350ηsec, after which the STROBE will go LOW. This would be followed by an approximate 350ηsec wait period,
after which the STROBE will go HIGH to initiate the reading of the TUNE INDEX BYTE which would be stable and read available for
approximately 350ηsec, after which the STROBE will go LOW. The next TUNE process would follow no sooner than approximately
22µsec after the completion of the last TUNE and would be triggered when the STROBE goes High.
