The Si570 Controller and Frequency Generator Kit #2

The Si570 Controller and Frequency Generator Kit #2

This standalone unit has a frequency range of 3.5Mhz to 1417.5Mhz (yes, 1.4Ghz) depending on the Si570 part used. I have tested it up to 1200Mhz which is as high as my scope will go. Really an amazing, low jitter, and very low spur levels chip. You can go to the SiLabs website and look at the specifications. All setup and control is via the rotary encoder knob and it's push button. Power is battery (3V) or external power (5V-12V). It's compatible with all Si570 CMOS and LVDS versions, single ended or differential output, and any default frequency. This makes an ideal signal source for SoftRocks and many other projects. The Si570 Controller and Frequency Generator Kit includes a 12 digit LCD frequency display, a programmed MC9S08QG8 microcontroller, and a rotary encoder for tuning. It can ordered with a CMOS Si570 chip which is speced at 3.5Mhz to 160Mhz. Using other LVDS Si570 parts, the frequency range can be extended up to 1.417Ghz.

The 20W HF Amplifier Kit #15 

My idea was to provide a good and low cost Amplifier for the HF bands (160m to 6m) which can be driven by a SoftRock SDR or any other low power driver and provide 20dBm of gain. Low power being defined as less than 1W. Some of the new SDR units supply less than 50mw and really need a little boost. This Amp uses well received RD16HHF1 RF MOSFETs which are each rated at 16W output for 12.5VDC at 30+MHz. These parts are quite robust and much better than the IRF510 Switching Power Supply MOSFETs used earlier, largely because of their low cost and availability. The other advantage of the RD16HHF1 is that the mounting tab is attached to the Drain pin which is at ground potential so no mica insulator is required. The Amplifier has a Signal Operated Switch (SOX) for CW QSK. I didnt really put it there for SSB ..but who knows (still better to use PTT). Did I mention good and low cost ?

N6HTV:
I built one of these for my Hermes board ( ANAN10 ) very linear and works great!!
