Z10046A High Gain Amplifier 
The complete Z10046A assembly and operation manual may be downloaded by clicking here or through my Documents page. Details on the optional enclosure may be downloaded by clicking here.

The Z10046A is a high gain (typically +23.5 dB) high performance (OIP > +42 dBm typically) broadband (50 KHz - 50 MHz) amplifier. Although designed as a receiver preamplifier, it may be used as a general laboratory amplifier as well. It is available as a kit or as an assembled amplifier printed circuit board. A custom enclosure will soon (expected in early September 2010) be available for the Z10046A.





The Z10046A printed circuit board is 3.5 inches x 2.5 inches (88.9mm x 63.5mm). Recommend minimum enclosure height is 1.5 inches (38.1 mm).

DC Supply

The Z10046A requires 10.0V at a current (depending upon user selected bias resistor options) from 320 mA to 400 mA. A suitable 10.0V regulator is supplied with the Z10046A and can be used with supply voltages of 12.5V to 20V. Proper heat sinking of the 10V regulator is required.


23.5 dB nominal at 1 MHz

Frequency Range

-3 dB points are 50 KHz � 50 MHz

Intermodulation [1]

Both second and third order output intercepts depend upon selected bias resistor options. OIP2 is typically +87 to +93 dBm; OIP3 is typically +42 dBm to +45 dBm. OIP2 also depends upon the care taken by the builder during assembly.

1 dB Compression Point

+24.7 dBm output at 1 MHz.

The Z10046A uses four Mini-Circuits GaLi-74+ microwave amplifiers in parallel/push-pull. This configuration significantly increases both 2nd and 3rd order intermodulation intercept and 1 dB compression point over the performance of a single GaLi-74+ device.
