MACOM recommends that VCC be powered on before VEE, and powered off after VEE. 6. 0.01 µF decoupling capacitors are required on the power supply lines. 7. VOPT is grounded in most cases when FETs are driven. To improve the intermodulation performance and the 1 dB compression point of GaAs control devices at low frequencies, VOPT can be increased to between 1 and 2 V. The nonlinear characteristics of the GaAs control devices will approximate performance at 500 MHz. It should be noted that the control current that is on the GaAs MMICs will increase when positive controls are applied. 8. When this driver is used to drive PIN diodes, VOPT is often set to +5 V, with VEE set to -5 V. Symbol Parameter Unit Min. Typ. Max.

Proper ESD control techniques should be used when handling these devices. |
