ANAN G2 Series · Ultra-High Dynamic Range

ANAN-G2E-20

20W HF & 6M Direct-Sampling SDR Transceiver

A ground-up reimagining of the ANAN-10. A redesigned receive and transmit chain built around a 16-bit ADC delivers ultra-high dynamic range — pulling weak signals out from beside the strongest ones on a crowded band. All the I/O on board. No expansion required.

The point of the radio

See the weak signal next to the strong one

Dynamic range is the distance between the quietest signal you can hear and the loudest one that won't desensitise the receiver. The G2E-20's redesigned front end widens that distance — so a faint DX caller survives right beside an S9+ neighbour.

01

16-bit direct-sampling ADC

The receiver digitises the antenna directly — no analog mixing stage to add spurs or limit headroom. More bits means a deeper, cleaner usable range from the noise floor up to full scale.

02

Redesigned Rx & Tx chain

On receive, an ultra-high dynamic range preamp feeds the 16-bit ADC for the cleanest possible headroom. On transmit, the chain has been completely reworked end to end.

03

Onboard broadcast-band filter

A dedicated BCB filter knocks down the strong AM broadcast energy that overloads wideband front ends — protecting dynamic range on the lower HF bands where it matters most.

04

PureSignal-ready

A dedicated feedback input (PS FB) lets adaptive pre-distortion clean up the transmitted signal, holding low IMD across the band even at full 20W output.

An update to the ANAN-10

Everything the 10 did — rebuilt

The G2E-20 keeps the compact, single-box character of the original ANAN-10 and answers what owners asked for next: more range, more power, and all the connections on board.

Receiver

Wider dynamic range

A 16-bit ADC and a reworked front end replace the original receive chain, lifting performance on bands packed with strong adjacent signals.

Transmit

20W, not 10W

Full 20W across every HF band and 15W on 6m — double the original’s output, with a cleaner, more linear PA chain behind it.

Connectivity

Rich I/O, on board

Three antenna ports, full audio, CW, OC control outputs and PTT are built in. Unlike the 10E, no expansion board is needed to reach them.

Connectivity

All of it. On the back. Out of the box.

The rear panel carries the complete station interface — antennas, reference, audio, keying, station control and PTT — with nothing held back behind an add-on board.

No expansion board. None.

On the ANAN-10E the full I/O lived on a separate add-on. The G2E-20 brings every connector onto the main panel — one box, fully wired, ready for the shack.

Signal chain

Antenna to Ethernet, in five stages

A direct-sampling architecture: the RF is filtered, digitised, and processed as data. Everything downstream of the ADC is software — so the radio improves with every release of the console.

01 / RF IN

Filtered front end

A broadcast-band filter knocks down strong AM energy before it reaches the converter.

02 / ADC

16-bit sampler

The antenna signal is digitised directly at full bandwidth — no analog down-conversion in the path.

03 / FPGA

DDC / DUC

On-chip digital down- and up-conversion handles channelisation, tuning and the panadapter stream.

04 / TX

20W linear PA

A redesigned, PureSignal-ready transmit chain drives 20W on HF, 15W on 6m with low distortion.

05 / HOST

Ethernet, Protocol 2

Gigabit LAN carries everything to the host over HPSDR Protocol 2 — local or fully remote.
