Please read this section before ordering, there have been changes to International shipping methods, etc

Instructions on assembling and use of the kits listed here are contained in the articles on this site, as well as close-up component layout pictures to aid in assembly. Surface-mount parts are used throughout, so it is helpful to have some experience in working with them.

You can order any of the items listed here using the shopping cart provided, or by sending an email (see contact information on the card below). Payment can be made with your PayPal account (if you have one), or a credit card of your choice at checkout. Parts are usually sent by Priority Mail the next business day for domestic. Priority mail within the USA has been reliable with transit times from 1 to 3 days.

For all international orders

PayPal does have volume agreements with both DHL and UPS for international shipments, and this will help lower your shipping costs if I am able to use it; however I will be able to use it only if you place your order using the default PayPal system used on this page. First class and priority mail has been unreliable for international shipments and is no longer recommended as an option.   
 

A 600 watt+ 33cm LDMOS amplifier (900 MHz band)

The Ultimate Amplifier Control Board

This photo is version 6.3 (current version 6.5 is the same functionally), designed for the highest powered amplifiers and mast-mounted LNA's, with the following functions and features:

• On-board sequencer for control of antenna relays, amplifier bias and power supply feeds, and driver RF hold-off
• High VSWR lockout that will accept either a negative or a positive trigger signal
• High temperature lockout that will bypass an overheated amplifier until it cools down to a safe temperature
• Temperature-sensitive fan control for normal cooling
• Driver RF blocking during antenna relay changeovers
• Internal regulator, which allows operation from power sources ranging from 12v to 50v
• LED indicator feeds for power, transmit, SWR lock and High Temperature lock
• Can be used as a controller for a mast-mounted LNA

A description of all connections into and out of the board is located here: v63control.htm

The temperature sensor, optional voltage reducer and indicator LEDs are supplied; the user must supply the vswr detector and the fan if those functions are to be used.

High Current DC FET Switch

12v and 28v models can switch up to 35 amps, 50v or 65v models more than 45 amps

Dual Microwave RF detector (38mm by 50mm)

Designed to be used with directional couplers lacking their own detectors. An explanation for the use of this board is explained in the Sampling RF Power article. By changing the values of the input attenuators, and the mounting positions of the diodes, the board can be configured for different power levels and output polarities. An assembly guide for the kit is here.

LNAs (preamps) and MMICs

LED Bar Graph Display

The current version changes R22 to a trimmer resistor, allowing the input sensitivity to be adjustable from less than 500mv to more than 15v.

Latching Relay Driver

Bias T for operating a remote LNA (preamp)

This board was designed to work with the IC-9700 on the low power side (up to 50w); the 9700 has the ability to enable a remote LNA by sending 12v down the coax to operate the LNA and its bypass relays; there are some other radios which can do the same (IC910H) and perhaps a few more I don't have experience with.

One of the shortcomings of the 12v supply is the 200 ma current limitation of the IC9700, but the bias T can "amplify" that current to a few amps if that much is needed (the technical write-up on its use is here)

The two versions of the board (for 144 through 432 and for 1296) are loaded and ready to put into your own enclosure with connectors of your choice. The pcb is small, just 1 x 2 inches (144-432 MHz version shown).
