MH203 The Communications Edge TM High Linearity Cellular-Band MMIC Mixer Product Features • • • • • • • +32 dBm IIP3 RF 800 – 960 MHz IF 200 – 350 MHz High-side LO configuration +17 dBm Drive Level Low Cost SOIC-8 Package No External Bias Required Applications • Mobile Infrastructure Product Information Product Description Functional Diagram The MH203 is a passive GaAs MESFET mixer that provides high dynamic range performance in a low cost SOIC-8 package. WJ’s MH203 uses patented techniques to realize +32 dBm Input IP3 at an LO drive level of +17 dBm when used in a simple application circuit as an upconverting or downconverting high-side LO 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 and GSM frequency bands. 1 8 2 7 3 6 4 5 Function LO IF & RF* GND Pin No. 2 7 1, 3, 4, 5, 6, 8 * External components (inductors & capacitors) are required to diplex the signal Specifications1 Parameters RF Frequency Range LO Frequency Range IF Frequency Range SSB Conversion Loss Noise Figure Input IP3 Input P1dB LO – RF Isolation LO – IF Isolation RF – IF Isolation Return Loss: RF Port Return Loss: IF Port Return Loss: LO Port LO Drive Level Units Min MHz MHz MHz dB dB dBm dBm dB dB dB dB dB dB dBm 800 1000 200 +28 25 50 Typ Max Comments 960 1310 350 9.5 8.2 9.0 +32 +16 30 65 25 -20 -17 -12 +17 See note 2 See note 3 See note 4 See note 4 Test conditions unless otherwise noted: 1. Performance is with the use of an application specific circuit (shown on page 4) with a high-side LO at +17 dBm in a downconverting application at 25° C. 2. Assumes LO injection noise is filtered at the thermal noise floor, -174 dBm/Hz, at the RF, IF, and Image frequencies. 3. IIP3 is measured with ∆f = 1 MHz with RFin = 0 dBm / tone. 4. The return loss is measured after the diplexer which splits the RF and IF signals from the mixer. Details of the diplexing circuit is shown on page 4.
