EXPERT ELECTRONICS SUNSDR2 DX [GEN5]
Latest 5th Generation Hardware Evolution — Condition: Like New
USED SELECTED EVALUATION SHEET
THE TOP-OF-THE-RANGE SDR AT ITS MAXIMUM HARDWARE MATURITY
If you're looking for the uncompromising performance of direct sampling DDC/DUC, this is the ultimate opportunity. We are offering the **SunSDR2 DX transceiver in the exclusive Gen5 (5th Generation) hardware revision**, in showroom conditions, **like new**. This is not an older series: the Gen5 introduces crucial circuit refinements that elevate spectral purity in transmission and thermal stability to unprecedented levels.
THE EXCLUSIVE IMPROVEMENTS OF THE GEN5 REVISION
-- OPTIMIZED LINEARITY AND IMD3
The Gen5 redesigns the final stage, bringing the transmit IMD3 to an exceptional value of **~37 dB** across all HF bands at full power (100W). Remarkably clean signal to avoid generating adjacent splatter in contests.
-- INCREASED POWER IN 6 METERS
Unlike the first series limited to 50W, the Gen5 hardware has been enhanced to deliver a stable **80W on the 6-meter band (Magic Band)**.
-- ANTI-CROSS-TALK SHIELDING AND ATU PROTECTION
The main PCB benefits from new internal shielding to reduce mutual coupling interference (cross-talk). Additionally, it includes dedicated ferrite beads on the flat cable between the PA and SDR for rock-solid stability when using external automatic antenna tuners.
-- PRECISION THERMAL READING
The temperature sensor has been repositioned at a critical point in the chassis to ensure instant readings and impeccable management of cooling airflows.
KEY HARDWARE PERFORMANCE
- 16-bit LTC2209 ADC: Pure 160 MSPS direct sampling with impressive Blocking Dynamic Range (BDR), ideal for extracting very weak signals amidst contest QRM.
- Two Independent Software Receivers: Each with its own Sub-RX, for a total of 4 simultaneous reception slices on different bands and frequencies.
- Integrated 2 Meter Module: Native output up to 8W in VHF (144 MHz) for local traffic, DX, or satellite without the need for external transverters.
- Galvanic Isolation LAN: Connection to the PC via RJ45 Ethernet port, eliminating ground loops and electromagnetic interference typical of standard USB cables at the root.
