Eight Ceyear up/downconverter models cover specific RF bands within 2.0-31 GHz, with 70 MHz or 70/140 MHz IF configurations, adjustable gain and 1 Hz frequency steps for test-system integration.
Compact, programmable and modular converters provide model-specific upconversion or downconversion. IF/RF bands, connectors and customization depend on the selected model and order.
The image shows representative series appearances. Connectors, accessories and appearance depend on the selected configuration; the group image is not the delivery quantity.

Selection and ordering notes
- Each model covers only its listed RF band, not continuous 2.0-31 GHz coverage in one unit. 70 MHz ±20 MHz / 140 MHz ±40 MHz denotes alternative IF configurations; confirm when ordering.
- Use gain, noise figure and flatness with their maximum-gain, ±20 MHz or full input/output-band conditions. p.t.p. means peak-to-peak.
- Phase noise is specified separately at 1 kHz, 10 kHz and 100 kHz offsets. In-band spurious response applies at 0 dBm output with offsets of 1 kHz and beyond.
- Manufacturer environmental and safety clauses are product specifications, not a claim of separate Shanghai Yanchuan certification. The factory quality document is not a metrology calibration certificate.
- For a quotation, specify manufacturer model, conversion direction, input/output bands, IF configuration, quantity and integration needs. Lead time and customization require configuration review.
