Data Sheet

4. ’Front end defined IM2’. LO set to 2145 MHz and AGC set to deliver a 5 MHz output of 0.5 Vp-p with a desired input CW @

frequency 2150 MHz of -45 dBm. Sum IM2 product from two undesired tones at 1.05 and 1.1 GHz at -25 dBm converted to 5 MHz

baseband with desired input removed. Baseband filter at 22 MHz bandwidth setting.

5. ’IM3’. AGC set to deliver an output of 0.5 Vp-p with an input CW @ frequency fc of -30 dBm. Two undesired tones at fc+55 and

fc+105 MHz at -11 dBm generating output intermodulation spur at 5 MHz. Baseband filter at 22 MHz bandwidth setting.

6. ’Front end defined’ variation in IP2 from two undesired tones at 1.05 and 1.1 GHz at 20 dBc relative to desired at 2.15 GHz

converted to 5 MHz baseband with LO tuned to 2.145 GHz with AGC set to deliver 0.5 Vp-p differential on desired, as desired

amplitude is varied from -45 dBm to -75 dBm.

7. Variation in IP3 product from two undesired tones at fc+55 and fc+105 MHz at 19 dBc relative to desired at fc converted to 5 MHz

baseband with LO tuned to desired at fc GHz with AGC set to deliver 0.5 Vp-p differential on desired, as desired amplitude is

varied from -30 dBm to -75 dBm.

8. AGC set to deliver an output of 0.5 Vp-p with an input CW @ frequency fc of -35 dBm. Input compression defined as the level of

interferer at 100 MHz offset, which leads to a 1 dB compression in gain.

9. The level of 2.01 GHz downconverted to baseband relative to 1.01 GHz with the oscillator tuned to 1 GHz, measured with no input

pre-filtering.

10. The level of second harmonic of 1.01 GHz input at -20 dBm downconverted to baseband relative to 2.01 GHz at -35 dBm with the

oscillator tuned to 2 GHz, measured with no input pre-filtering gain set to deliver 0.5 Vp-p on 2.01 GHz CW signal. RF gain adjust

= +4 dB, prefilter = +4.2 dB and postfilter = 0 dB RFG = 1, BA1 = 0, BA0 = 1, BG1 = 0, BG0 = 0

11. Within 0-100 MHz band, RF input set to deliver 0.5 Vp-p on output. RF gain adjust = +4 dB, prefilter = +4.2 dB and postfilter

= 0 dB RFG = 1, BA1 = 0, BA0 = 1, BG1 = 0, BG0 = 0

12. Two input tones at fc+50 and fc+100 MHz at -9 dBm generating output intermodulation spur at fc.

13. Sum IM2 product from two input tones at 1.05 and 1.1 GHz at -9 dBm converted to 2150 MHz.

14. PLL loop bandwidth ~15 kHz, comparison frequency 1 - 2 MHz.

15. Integrated rms LO jitter measured from 1 kHz to 15 MHz, PLL loop bandwidth 15 kHz. Varactor voltage = 3.5 volts.

16. RSD = 0 for 8 MHz <= fset <= 20 MHz, RSD = 1 for 20 MHz <= fset <= 35 MHz.
