Proper ESD control techniques should be used when handling these static sensitive devices. 2. Exceeding any one or combination of these limits may cause permanent damage to this device. 3. MACOM Technology Solutions does not recommend sustained operation near these survivability limits. 4. Operating at nominal conditions with TJ ≤ 150°C will ensure MTTF > 1 x 106 hours. 2 • North America Tel: 800.366.2266 • Europe Tel: +353.21.244.6400 • India Tel: +91.80.43537383 • China Tel: +86.21.2407.1588 Visit www.macomtech.com for additional data sheets and product information.

MAAP-011106 Power Amplifier, 71 - 86 GHz Calibration Plane All data was measured on die with 200 µm pitch probes. The calibration plane is at the middle of the through, 178.5 µm from the middle of the RF pad. Rev. V1 App Note [3] Wire Bonding - The loop height of the RF bonds should be minimized. Where the die is mounted above the PCB, it is recommended to use Reverse Ball-Stitch-on-Ball bonds (BSOB). If the die is mounted inside a cavity on the board, Forward Loop bonding may result in a lower loop height. V-shape RF bond with two wires (diameter = 25 µm is recommended for optimum RF performance. RF bond wire length to be minimized to reduce the inductance effect. Simulations suggest no more than 300 µm. Substrate RF pad can be optimised to improve the Microstrip to MMIC bond transition as shown in the example below. App Note [1] Biasing - All gates should be pinched -off (VG < -1 V) before applying drain voltage (VD = 4 V). Then the gate voltages can be increased until the desired quiescent drain current is reached in each stage. The recommended quiescent bias is VD = 4 V, ID1 = 60 mA, ID2 = 120 mA, ID3 = 240 mA and ID4 = 300 mA. The performance in this datasheet has been measured with fixed gate voltage and no drain current regulation under large signal operation. It is also possible to regulate the drain current dynamically, to limit the DC power dissipation under RF drive. To turn off the device, the turn on bias sequence should be followed in reverse. App Note [2] Bias Arrangement - Each DC pin (VD1,2,3,4 and VG1,2,3,4) needs to have bypass capacitance (120 pF and10 nF) mounted as close to the MMIC as possible. 5 • North America Tel: 800.366.2266 • Europe Tel: +353.21.244.6400 • India Tel: +91.80.43537383 • China Tel: +86.21.2407.1588 Visit www.macomtech.com for additional data sheets and product information.
