WJ's MH202 uses patented techniques to realize +30 dBm Input IP3 at an LO drive level of +17 dBm when used in a simple application circuit as an upconverting configuration. This single monolithic integrated circuit does not require any external baluns or bias elements. Typical applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in 2.5G and 3G systems using the cellular GSM frequency band. 1 8 2 7 3 6 4 5 Function Pin No. LO IF & RF* GND 2 5 1,3,4,6,8 * 4 external components (inductors & capacitors) are required to diplex the signal Specifications Parameters1 Frequency Range: RF LO IF SSB Conversion Loss Noise Figure Input IP32 Input P1dB Isolation: L-R L-I R-I Return Loss: LO Port LO Drive Level Units Minimum MHz MHz MHz dB dB dBm dBm 890 640 200 Typical Maximum Comments 960 760 250 10 9.5 10 +30 TBD 30 55 dB dB dB dB TBD -5 +17 dBm 1. Data was taken using an application board shown on the following page, with a low side LO at +17 dBm in an upconverting application at 25C. 2. Input IP3 was measured with two tones with an input power of -5 dBm / tone separated by 1 MHz.
