400MHz 2.5GHz Upconverter Mixers
Output Frequencies: 400MHz 2.5GHz Noise Figure: 9.3dB (900MHz, MAX2671) +2.7V +5.5V Single Supply High Output Intercept Point (OIP3) 5.9dBm 4.8mA (MAX2660) 7.1dBm 8.3mA (MAX2661) 0.7dBm 3.0mA (MAX2663) 9.6dBm 11.8mA (MAX2671) 7.6dBm 20.5mA (MAX2673) Shutdown Mode Ultra-Small Surface-Mount Packaging
miniature, low-cost, low-noise upconverter mixers designed low-voltage operation ideal portable consumer equipment. Signals input port mixed with signals local oscillator (LO) port using double-balanced mixer. These upconverter mixers operate with input frequencies between 40MHz 500MHz, upconvert output frequencies high 2.5GHz. These devices offer wide range supply currents output intercept levels optimize system performance. Supply current essentially constant over specified supply voltage range. Additionally, when devices typical configuration with SHDN shutdown mode reduces supply current less than 1µA. MAX2660/MAX2661/MAX2663/MAX2671 offered space-saving 6-pin SOT23 package. applications requiring balanced ports, choose MAX2673 8-pin µMAX package.

_Detailed Description
2.5GHz double-balanced upconverter mixers designed provide optimum linearity performance specified supply current. These upconverter mixers single-ended port connections, except MAX2673, which uses differential port. on-chip bias cell provides low-power shutdown feature. Selector Guide device features comparison.
Power Supply SHDN Bypassing
Proper attention supply bypassing essential high-frequency circuit. Bypass with 10µF capacitor parallel with capacitor (Table separate vias ground plane each bypass capacitors minimize trace length reduce inductance. separate vias ground plane each ground pin. low-inductance ground connections. Decouple SHDN with 100pF capacitor ground minimize noise internal bias cell. series resistor (typically 100) reduce coupling high-frequency signals into SHDN pin.
_Applications Information
Local-Oscillator (LO) Input
input single-ended broadband port with return loss better than from 600MHz 2.5GHz. signal mixed with input signal, resulting upconverted output appears RFOUT pin. AC-couple with capacitor having less than reactance frequency. MAX2671/MAX2673 include internal buffer require signal ranging from -10dBm +5dBm, while MAX2660/MAX2661/MAX2663 require signal ranging from -5dBm +2dBm.
_Layout Issues
well-designed board essential part circuit. best performance, attention powersupply issues well layout RFOUT matching network.
Power-Supply Layout
minimize coupling between different sections ideal power-supply layout star configuration with large decoupling capacitor central node. traces branch from this central node, each going separate node board. each trace bypass capacitor that frequency operation. This arrangement provides local decoupling each pin. high frequencies, signal leaking supply sees relatively high impedance (formed trace inductance) central node, even higher impedance other supply pin, well impedance ground through bypass capacitor.
Input
MAX2660/MAX2661/MAX2663/MAX2671 have single-ended input port, while MAX2673 differential input port high-performance interfaceto-differential filters. AC-couple pin(s) with capacitor. typical input frequency range 40MHz 500MHz. further information, Port Impedance Frequency graph Typical Operating Characteristics.
Output
output frequency range extends from 400MHz 2.5GHz. RFOUT high-impedance, open-collector output that requires external inductor proper biasing. optimum performance, implement impedance-matching network. configuration values matching network depend frequency, performance, desired output impedance. assistance choosing components optimal performance, Table well Output Impedance Frequency graph Typical Operating Characteristics.
Impedance-Matching Network Layout
RFOUT matching network very sensitive layout-related parasitics. minimize parasitic inductance, keep traces short place components close possible chip. minimize parasitic capacitance, cutouts ground plane (and other plane) below matching network components.
