This document is the MAX2043 evaluation kit manual, which introduces the features and characteristics of the evaluation board, including the evaluation board's function, test method, circuit schematic, BOM list, etc.
The MAX2043 Evaluation Kit is a fully assembled, factory‑tested board that simplifies evaluation of the MAX2043 UMTS/WCDMA, DCS, PCS, and WiMAX base‑station up/down‑conversion mixer. It includes 502 SMA connectors on the input and output ports and covers RF frequencies from 1700 MHz to 3000 MHz, LO frequencies from 1900 MHz to 3000 MHz, and IF frequencies from DC to 350 MHz.
The manual contains a quick‑start guide, a list of required test equipment, detailed connection and setup procedures, mixer testing steps, layout considerations, and a complete schematic and PCB layout. Component part numbers, ordering information, and a bill of materials are also provided.
| RF Frequency Range | 1700 MHz to 3000 MHz |
|---|---|
| LO Frequency Range | 1900 MHz to 3000 MHz |
| IF Frequency Range | DC to 350 MHz |
| Conversion Loss | 7.5 dB |
| Input IP3 (Downconversion) | +31 dBm |
| Input 1 dB Compression Point | +23 dBm |
| Noise Figure | 7.8 dB |
| LO Drive Range | -3 dBm to +6 dBm |
| SPDT LO Switch Isolation | 43 dB |
| SPDT LO Switch Switching Time | 50 ns |
Connecting TP3 (LOSEL) to ground selects LO2; leaving TP3 open selects LO1.
Set the RF source to 1900 MHz at 0 dBm, LO1 to 2100 MHz at 0 dBm, calibrate the power meter at 2100 MHz, and measure the IF output at 201 MHz; the expected level is about –10.5 dBm, reflecting a 7.5 dB conversion loss.
