825MHz 915MHz, SiGe High-Linearity Active Mixer
MAX9982 high-linearity mixer integrates local oscillator (LO) switch, driver, active mixer. On-chip baluns allow single-ended inputs. active mixer eliminates need additional amplifier because mixer provides typical overall conversion gain 2dB. MAX9982 active mixer optimized meet demanding requirements GSM850, GSM900, CDMA850 base-station receivers. This mixer provides exceptional linearity with input third-order intercept point (IP3) greater than +26dBm. integrated driver allows wide range drive levels from -5dBm +5dBm. addition, built-in switch enables rapid selection less than 250ns, needed transceiver designs.

Detailed Description
MAX9982 downconverter mixer designed CDMA base station receivers with frequency between 825MHz 915MHz. implements active mixer that provides overall conversion gain receive path, removing need additional amplifier. mixer also excellent input measuring +26.8dBm. device also features integrated baluns that allow mixers driven with single-ended signals.
Inputs
MAX9982 input (RF) that internally matched requiring external matching components. 33pF DC-blocking capacitor required input because input internally shorted ground through balun. input frequency range 825MHz 915MHz.
Inputs
mixer used either high-side low-side injection applications with frequency range
825MHz 915MHz, SiGe High-Linearity Active Mixer
725MHz 1085MHz. internal switch allows switching between single-ended ports; this useful fast frequency changes/frequency hopping. switching time less than 250ns. switch controlled digital input (LOSEL) that when high, selects when low, selects LO2. Internal buffers allow wide power range ports. signal power vary from -5dBm +5dBm. internally matched only 33pF DC-blocking capacitor required each port.
Bias Circuitry
Connect bias resistor from RFBIAS ground mixer bias current. nominal resistor value sets input +26.8dBm supply current 168mA.

Applications Information
Layout Considerations
properly designed board essential part RF/microwave circuit. Keep signal lines short possible reduce losses, radiation, inductance. best performance, route ground traces directly exposed paddle underneath package. Solder exposed bottom device package evenly board ground plane provide heat transfer path along with grounding.
Outputs
This mixer frequency range 70MHz 170MHz. differential output ports require external pullup inductors resonate differential on-chip capacitance 1.8pF. Typical Application Circuit recommended component values optimized 70MHz 100MHz. Higher frequencies optimized reducing values Removing ground plane from underneath reduces parasitic capacitive loading improves VSWR.
Power Supply Bypassing
Proper voltage supply bypassing essential highfrequency circuit stability. Bypass each with 0.1µF capacitor. Bypass placing 33pF (C2) ground within mils pin.
