Description

The C2306 is a flexible, high intercept, frequency conversion GaAs MMIC packaged in a 14 pin SOIC

package. The MMIC is usable as an upconverter or downconverter mixer. Each subcircuit is brought out on

separate pins to allow for custom filtering on the IF/RF mixer interstage or custom matching for specific bands.

Broadband parallel feedback networks are used on the gain and LO driver stages and the mixer is a singly

balanced two diode mixer. The FET source of the IF amplifier stage (IF BIAS) is accessible for AC bypassing

which allows for current reduction with self bias circuitry. The gain and DC current is broken up as follows:

LO AMP gain = 11dB; current = 27 mA, IF AMP gain = 17dB, current = 60mA, Mixer conversion loss = -

6dB. Simple external matching circuits can be implemented for all ports to achieve VSWR’s < 2:1 over

moderate bandwidths of less than 400MHz.

Recommended LO IN Port Matching

The LO IN port of the C2306 can be matched into 50 ohms with a lossy network. At 3dBm drive, the

unmatched port is at Z = 5 –15j ohms at 2.278 GHz. Also of note is that this impedance varies somewhat with

the LO drive level. Therefore a narrow band high Q network is not recommended due to inherent

manufacturing variation in LO drive available. The simple network below matches this port over an ~ 10%

bandwidth.

Biasing and Electrical Ground/

Thermal Considerations

Pins 3,4,5,10 and 12 should have ground vias straddling

both sides of the pin solder contact. This insures good

electrical and thermal grounding. If the IF AMP is run at

I_dss(DC Grounded IF BIAS pin 14), this pin should be

grounded as described above. It is recommended that a

continuous ground plane be present under the package

to lower pin impedance and maintain similarity with the

matching environment used in the schematic in the

Application Information section. Bias for the IF amplifier

is supplied thru IF OUT pin 14. All ports are DC coupled

to the IC. Pins 2,6 and 13 should be kept at 0V DC to

maintain proper gate voltages. Pin 9 is internally biased

at 5V under normal operation and requires an external DC

block.
