DC ELECTRICAL CHARACTERISTICS—CW MIXER MODE
(
Typical Application Circuit, Figure 7. VCC = VREF = 4.75V to 5.25V, TA =0
°C to +70°C, VGND = 0V, LOW_PWR = 0,
M4_EN = 0, CW_FILTER = 0 or 1, TEST_MODE = 0, PD = 0, CW_VG = 0, CW_M1 = 0, CW_M2 = 0, no RF signals applied,
capacitance to GND at each of the VGA differential outputs is 60pF, differential capacitance across the VGA outputs is 10pF,
RL =1k
Ω, CW mixer outputs pulled up to +11V through four separate ±0.1% 115Ω resistors. Typical values are at VCC = VREF = 5V,
TA = +25
°C, unless otherwise noted.) (Note 2)
