3.5GHz Downconverter Mixers
with Selectable LO Doubler
Note 4: Conversion gain does not include output balun losses, typically 0.3dB at 300MHz on the MAX2683 EV kit and 0.8dB at
900MHz on the MAX2684 EV kit.
Note 5: IIP3 measured with two tones at 3605MHz and 3610MHz, -20dBm per tone, fIF = 300MHz.
Note 6: IIP2 measured with fRFIN = 3450MHz, PRFIN = -20dBm, fIF = 300MHz.
Note 7: Input match optimized for best return loss at fRF = 3600MHz.
Note 8: Over specified RF input frequency range with matching network.
Note 9: Over specified LO input frequency range.
Note 10: IIP3 measured with two tones at 3605MHz and 3610MHz, -20dBm per tone, fIF = 900MHz.
Note 11: IIP2 measured with fRFIN = 3150MHz, PRFIN = -20dBm, fIF = 900MHz.
Typical Operating Characteristics
(MAX2683/MAX2684 EV kit, VCC = +5V, RBIAS = 1.2kΩ, ENX2 = GND, fRF = 3.6GHz, PRF = -20dBm, fLOX2 = 1650MHz for MAX2683 or
fLOX2 = 1350MHz for MAX2684, PLO = -5dBm, all input/output ports terminated in 50Ω, IFOUT+ and IFOUT- matched to single-ended
50Ω load, TA = +25°C, unless otherwise noted.)
