1700MHz to 3000MHz High-Linearity, Low LO Leakage Base-Station Rx/Tx Mixer

Maxim Integrated 

1700MHz to 3000MHz High-Linearity,

Low LO Leakage Base-Station Rx/Tx Mixer

AC ELECTRICAL CHARACTERISTICS (Upconverter Operation)

(MAX2043 Typical Application Circuit, VCC = +4.75V to +5.25V, PLO = -3dBm to +3dBm, PIF = 0dBm, fRF = 1700MHz to 3000MHz,

fLO = 1900MHz to 3000MHz, fIF = 200MHz, fRF = fLO - fIF, TC = -40°C to +85°C, unless otherwise noted. Typical values are at VCC =

+5V, PIF = 0dBm, PLO = 0dBm, fRF = 2170MHz, fLO = 2260MHz, fIF = 90MHz, TC = +25°C, unless otherwise noted.) (Note 3)

Note 1: All limits reflect losses of external components. Output measurement taken at IF port of Typical Application Circuit.

Note 2: The lower IF frequency limit of 0MHz is limited by the external IF transformer.

Note 3: Measured with external LO source noise filtered so its noise floor is not a contributor. Measured with: fRF = 2000MHz,

fBLOCKER = 2100MHz, fLO = 2190MHz, using a 190MHz SAW filter on the IF port. This specification reflects the effects of

all SNR degradations in the mixer, including the LO noise as defined in Maxim Application Note 2021.

Note 4: Maximum reliable continuous input power applied to the RF or IF port of this device is +15dBm from a 50Ω source.

Note 5: Typical Operating Characteristics show LO drive extended to +6dBm

Note 6: Measured IF port at IF frequency. fLO1 and fLO2 are offset by 1MHz.

Note 7: IF return loss can be optimized by external matching components.

Typical Operating Characteristics

(MAX2043 Typical Application Circuit, C2 not installed, RFTAP = GND, VCC = +5.0V, PLO = 0dBm, LOSEL = “0” (LO2 selected), PRF =

0dBm, fLO > fRF, fIF = 200MHz, unless otherwise noted.)
