Ground connection. Keep traces physically short and connect immediately to the ground plane for best performance. Amplifier RF input. The amplifier does not contain internal DC blocking and, therefore, should be externally DC blocked before connecting to any device which has DC present or which contains a DC path to ground. Power down control voltage. When this pin is at 0 V, the device will be in power down mode, dissipating minimum DC power. When this pin is at 3 V the device will be in full power mode delivering maximum gain and output power capability. This pin should not, in any circumstance, be higher than 3.3 V. This pin should also have an external UHF and HF bypassing capacitor. Typically VBIAS = VPD = 3.0 V. Amplifier RF output. This is an unmatched collector output of the final amplifier transistor. Bias for the final power amplifier output transistor must also be provided through one of these pins. Pins 9 and 10 should be used for the RF output with a matching network that presents the optimum load impedance to the PA for maximum power and efficiency, as well as providing DC blocking at the output. RF output power gain control 8 dB bit (see specification table for logic). The control voltage at this pin should never exceed 3.3 V and a logic high should be at least 1.7 V. This pin should also have an external UHF bypassing capacitor. See note. RF output power gain control 16 dB bit (see specification table for logic). The control voltage at this pin should never exceed 3.3 V and a logic high should be at least 1.7 V. This pin should also have an external UHF bypassing capacitor. See note. Positive supply for the first stage (driver) amplifier. This is an unmatched transistor collector output. Positive supply for the bias circuits. This pin should be bypassed with a single UHF capacitor, placed as close as possible to the package. Typically, VBIAS = VPD = 3.0 V. Note: The 8 dB and 16 dB gain steps are approximate for small signal operation. As the device compresses, the values of the gain steps compress as well. The output power table on page two shows the effect of the gain steps for saturated (0 dBm input) operation. 4 of 8 7628 Thorndike Road, Greensboro, NC 27409-9421 · For sales or technical support, contact RFMD at (+1) 336-678-5570 or [email protected].
