Notes
1. V_p = V_q = 44 dBmV;
f_p = 55.25 MHz; f_q = 493.25 MHz;
measured at f_p + f_q = 548.5 MHz.
2. Measured according to DIN45004B:
f_p = 540.25 MHz; V_p = V_o;
f_q = 547.25 MHz; V_q = V_o −6 dB;
f_r = 549.25 MHz; V_r = V_o −6 dB;
measured at f_p + f_q − f_r = 538.25 MHz.
3. The module normally operates at V_B = 24 V, but is able to withstand supply transients up to 30 V.
