Zarlink Semiconductor Inc.
Note 1:
AGC set to deliver an output of 0.5Vp-p with an input CW @ frequency fc of -30 dBm, undesired tones at fc+146 and fc+155
MHz @ -15 dBm, generating output IM spur at 9 MHz. Measured relative to unwanted signal.
LO set to 2145 MHz and AGC set to deliver a 5 MHz output of 0.5Vp-p with an input CW @ frequency 2150 MHz of –40 dBm.
Undesired tones at 1.05 and 1.1 GHz at -25 dBm generating IM spur at 5 MHz baseband. Measured relative to unwanted
signal.
AGC set to deliver an output of 0.5Vp-p with an input CW @ frequency fc of -30 dBm. Two undesired tones at fc+205 and
fc+405 MHz at -12 dBm, generating output IM spur at 5 MHz.
AGC set to deliver an output of 0.5Vp-p with an input CW @ frequency fc of -30 dBm. Two undesired tones at fc+55 and
fc+105 MHz at -15 dBm, generating output IM spur at 5 MHz.
The level of 2.01 GHz down converted to baseband relative to 1.01 GHz with the oscillator tuned to 1 GHz.
The level of second harmonic of 1.01 GHz at -20dBm downconverted to baseband relative to 2.01 GHz desired signal at
-35dBm with agc set to give 0.5Vp-p output. LO frequency = 2 GHz.
Reference VCO gain value for loop filter calculations. Using this recommended value then takes into account VCO switching
and automatic charge pump current variations.
Two input tones at fc+50 and fc+100 MHz at -12 dBm, generating output IM product at fc.
IM2 product from two input tones at 1.05 and 1.1 GHz at -16 dBm, generating IM product at 2150 MHz.
Note 10: Crystal specifications vary considerably and significantly effect the choice of external oscillator capacitor values. Each
application may require separate consideration for optimum performance.
