3.15V ... 6V

4.75V … 5.25V

VCO Input (FMCW, FSK)

not available

yes

IF highspeed DC output

not available

yes

IF output DC offset (typ.)

1.5V

2.5V

RSW rapid sleep wakeup

yes (sleep current typ 7mA)

Sensitivity (typical)

-140dBc

-141dBc

-96dBV/Hz

SNR Signal-to-noise ratio

same signal for comparison

K-MC1_LP has similar sensitivity as

K-MC1 despite the higher noise level.

5dB/div → SNR = 32dB

5dB/div → SNR = 33dB

Worst case 1/f Noise

comparison

Low current technology of K-MC1_LP

requires high sensitive mixer diodes in

order to get same sensitivity as K-MC1.

Higher 1/f noise is caused by these

diodes and by aliasing of internal

switching noise.

Please note, that higher K-MC1_LP

noise does not significantly affect the

SNR (signal-to-noise ratio). See

diagrams above for SNR.
