| MH205 High Linearity Cellular-Band MMIC Mixer Product Information Product Features * * * * * * * * +33 dBm IIP3 RF 800 - 915 MHz IF 70 - 120 MHz ISO & EPC compliant Low-side LO configuration +17 dBm Drive Level Low Cost SOIC-8 Package No External Bias Required Product Description The MH205 is a passive GaAs MESFET mixer that provides high dynamic range performance in a low cost SOIC-8 package. Its robustness and ease of use make it an ideal candidate for the core of any RFID reader application. It is compliant with EPC and ISO standards. Functional Diagram 1 8 7 2 3 6 Applications * RFID: UHF * Readers * Industrial * Portable WJ's MH205 uses patented techniques to realize +33 dBm Input IP3 at an LO drive level of +17 dBm when used in a simple application circuit as an upconverting or downconverting low-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 various current and next generation RFID technologies such as EPC, ISO, ETSI, and ANSI. Their small size makes them ideal for PCMCIA applications. 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 * Handheld 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 MHz MHz MHz dB dB dBm dBm dB dB dB dB dB dB dBm Min 800 700 70 Typ Max 915 845 120 9.5 Comments +28 30 47 8.7 9.2 +33 +18 37 51 15 12 14 8 +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 low-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.
