Product Description
The HMJ9 is a high dynamic range,
GaAs FET mixer. As an upconverter,
this active FET mixer realizes a typical
third order intercept point of +35 dBm at
an LO drive level of +17 dBm. The
HMJ9 comes in a low cost, J-lead
package. Typical applications include
frequency up/down conversion for
receivers and transmitters used in cellular
communications systems.
