Notes On Electrical Characteristics:- All RF measurements are made with appropriate matching to the input or output
impedances, such as balun transformers, and levels refer to matched 50ohm ports (see figure 3 for test circuit)
1.
RF input impedance (series) without input matching components connected - expressed as Real impedance with reactive
inductor value. Measured at 1575.42MHz.
2.
Input matched to 50ohm, output loaded wlth 600ohm differential
3.
Maximum Stage 3 input signal amplitude for correct AGC operation = 20mV rms.
4.
VCO regulator voltage measured with respect to Vcc (OSC) - pin 5.
5.
The OPCLK outputs are differential and are referenced to VDD.
6.
Minimum gain requirement expressions:
-7dBm < -174dBm/Hz + 19dB + G1 + G2 + G3 - 21dB + 63dB
where -7dBm = typical IF Output level with AGC active (equivalent to 100mV rms)
-174dBm/Hz = background noise level at RF input
19dB = sum of LNA gain and noise figure
-21dB = total loss in 175MHz and 35MHz filters
63dB = summation of noise over a 2MHz bandwidth
Rearranging the above expression gives G1 + G2 + G3 > 106dB.
7.
This parameter is not production tested.
8.
This impedance is toleranced at +/-30% and is not production tested.
9.
Roll off occurs in on-chip capacitive coupling IF Output to input of ADC circuit. Not measurable at IF Output.
10. CW input on pins 47 & 48 of 35.42MHz at 7mV rms.
11. This input impedance applies to the typical input level. The impedance is level dependent and is not tested or guaranteed.
