FUNCTIONAL BLOCK DIAGRAM
Mitsubishi Electric Corporation puts the maximum effort into making semiconductor products better and more reliable, but there is always the possibility that trouble may occur with them. Trouble with semiconductors may lead to personal injury, fire or property damage. Remember to give due consideration to safety when making your circuit designs, with appropriate measures such as (i)placement of substitutive, auxiliary, circuits, (ii)use of non-flammable material or (iii)prevention against any malfunction or mishap.

The Vref pin should be operated under the pulsed condition in order to achieve specified performance. The recommended pulse condition is shown in P. 12. Attenuator control pin. The ATT controller offers through mode with a Vcont of 0V, and offers attenuation mode with a Vcont of 3V. The backside ground paddle should be connected to the external ground plane which provides heat sinking.

3.3-3.6GHz HBT Integrated Circuit
APPLICATION CIRCUIT IN EVALUATION BOARD
NOTE: A properly designed PC board is essential to any RF/microwave circuit. Be sure to use controlled impedance lines on all high-frequency inputs and outputs. A ground plane should be present on both the top and bottom of the PC board and plated-through via holes connecting the top and bottom ground planes should be distributed (See page 10). GND pins and ground paddle of the package should be connected to the bottom ground plane with plated-through via holes close to the package. To improve the heat resistance, place as plated-through via holes as possible under the ground paddle (See page. 13). The output matching circuit is not included in the device so that users can determine the optimum output performance on their boards at the frequencies of interest. Since the circuit dictates the RF characteristics of PA, especially distortion, it should be designed with great care to obtain its maximum ability. The schematic of the evaluation board is shown above. Capacitors, C4~C6, C8, C9 and C15, and controlled impedance lines are optimized to realize broad-band output matching at frequencies from 3.3 to 3.6GHz. Input and output matching networks are very sensitive to layout-related parasitics. Suggested component values may vary according to layout and PC board material. Since the high-impedance feed lines for Vc3 and Vc4 are not included in the device, both the lines have to be laid out on the PCB. In layout design, please refer to the reference circuit of the feed lines which affect the distortion. Each Vc node on the board should have its own decoupling capacitor to minimize supply coupling from one section of the MMIC to another. A bypass capacitor with low ESR at the RF frequency of operation is located close to the package to reject the RF noise. In addition, a large decoupling capacitor is located on each power supply line to reject low frequency noise.

* * *
This figure shows the timing chart between Vref and input signal. Only while the reference voltage is 2.85V, the device transmits the input signal (*1). We usually set the delay time at 0ms in our EVB evaluation because of short set-up time. However set-up time often depends on bypass capacitors of PCB. Therefore, please give appropriate delay time (e.g. about the rise time of Vref) between the rise edge of Vref and that of the input signal . * We recommended the device operate with less than 50% duty cycle of a 5msec period in order to ensure specified reliability. *1: In case the device is operated under the Vref conditions of more than 50% duty cycle, self-heating will cause reliability problem, thereby degrading both power gain and EVM performance unexpectedly.

Calibrate power meters at input/output ports on the EVB. Apply DC voltage to Vcc (Vcb1-3, Vcb4, Vc1~Vc4) and Vcont, where pulsed power supply should be applied to Vref for pulsed operation. . Monitor DC output voltage from Vdet using an oscilloscope or a multimeter.
GND->Vcc->Vref->Vcont (1)Apply 6V to Vcc, where stepping up from 0 to 6V is preferable. (2)Supply pulsed voltage between 0 and 2.85V for Vref. Please check the voltage level of Vref close to EVB and the timing chart between Vref and input signal using an oscilloscope. Also please do not apply supply voltage exceeding 3V(absolute maximum rating) to the Vref terminal. (3)Supply Vcont with 3V for the attenuation mode. In the thru-mode, apply 0V to Vcont or keep it open. Vcont->Vref->Vcc->GND The reverse procedure is recommended for bias off.

HANDLING PRECAUTION
1)
Work desk, test equipment, soldering iron and worker should be grounded before mounting and testing. Please note that electric discharge of GaAs HBT is much more sensitive than that of Si transistor. Handling without ground possibly damages GaAs HBT. The surface of a board on which this product is mounted should be as flat and clean as possible to prevent a substrate from cracking by bending this product.
2)
3)
Recommended IR reflow soldering condition is shown as follows. (Max. two times)
Peak 245deg.C
240deg.C 225deg.C (PKG Surface temp.)
10 sec 70 sec
Max. Ramp Up Rate 3deg./sec.
180 10 deg .C 120 20sec Max. Ramp Down Rate
4)
6deg./sec.
Handling precaution at high temperature In case of heating this product, please keep the same heat profile as recommended reflow one. Please note that crack, flaw or modification may be generated if epoxy resin part is handled with tweezers and etc. at high temperature.
5)
Cleaning condition Please select after confirming administrative guidance, legal restrictions, and the mass of the residual ion contaminant etc., and use it. After soldering, please remove the flux. Please take care that solvent does not penetrate into this product. GaAs HBT contains As(Arsenic). This product should be dumped as particular industrial waste.
