MAX2660 400MHz - 2.5GHz Upconverter Mixer Data

Data for the MAX2660 RF mixer including the mixer type, whether it is balanced double balanced, etc, electrical parameters, pinout, package type and many other key datasheet details.

The MAX2660 miniature, low-cost, low-noise upconverter mixer is designed for low-voltage operation and are ideal for use in portable consumer equipment.

Signals at the IF input port are mixed with signals at the local oscillator (LO) port using a double-balanced mixer.

This upconverter mixer operates with IF input frequencies between 40MHz and 500MHz, and upconvert to output frequencies as high as 2.5GHz.

Explanation of RF mixer parameters

Parameter	Explanation
Input Frequency range	Most RF mixer have a frequency range over which they can operate. As a result of the components used, this might include both upper and lower limits.
IF Frequency range	This is a specification used on some RF mixers and it defines the frequency range for the IF output.
Conversion gain / loss	Active miers often offer a level of gain between the RF input and the IF output. Passive mixers will introduce a loss. The conversion gain, measured in dB is a measure of this.
Noise figure	This is an important factor for low noise systems and it is a measure of te noise introduced. It is expressed in terms of dB.
LO to RF isolation	It is important that the normally high level local oscillator signal is isolated from the RF input, otherwise spurious signals might be generated.. This parameter gives a measure of the isolation or reduction in the LO signal from the LO input to the RF input and it is expressed in dB.
LO to IF isolation	This is the isolation, i.e. reduction in the level of the LO signal between the local oscillator input to the IF output expressed in dB.
RF to IF isolation

Parameter	Explanation
Output third order intercept, OIP3	The Third Order Intercept Point (IP3) for an RF mixer is a theoretical power level at the input (IIP3) or output (OIP3) where the power of the desired signal and the third-order intermodulation distortion (IMD3) products become equal.
Output 1dB compression point	The 1dB compression point of an RF mixer is the input power level at which the desired output signal power drops by 1 dB below the level expected from the ideal linear conversion gain.
RF input power	The maximum power level that can be applied to the RF input for the mixer to perform within its specifcation.
LO input power	The recommended power level for the local oscillator signal at the LO input.
IF output power
Maximum LO input VSWR	In order to achieve its required performance the local oscillator source impedance must match the required impedance. This specification gives the maximum VSWR for it to reach its specified performance.
Max output spurious emissions	The maximum level is unwanted spurious signals relative to the wanted one expressed in dB.

These are the main RF mixer parameters that have been included in our list. There are others, but the ones included are the main ones encountered.
