5STP24L2800 Price| Pin | Function | Description | Interface Schematic | | 1 | RFl IN | RF input pin. This pin is internally connected to the bias circuits. An external DC blocking capacitor is required. The value of this capacitor depends on the actual operating frequency. | | | 2 | GND | Ground connection. Keep the connection to the backside ground plane as short as possible, by placing the vias close to the pin. | | | 3 | GND | Same as pin 2 | | | 4 | PD | Power down control voltage. When this pin is at OV, the device will be in power down mode, dissipating minimum DC power. When this pin is at Vcc (but not higher than 5.OV max), the device will be in full power mode delivering maximum gain and output power capability. This pin may also be used to perform some degree of gain control or power con- trol when set to voltages between OV and Vcc or 5.OV, whichever is the lowest. It is not optimized for this function so the transfer function is not linear over a wide range as with other devices specifically designed for analog gain control. However, it may be usable for coarse adjustment or in some closed loop AGC systems. This pin should not, in any circum- stance, be higher in voltage than Vcc. This pin should also have an external bypassing capacitor. | | | 5 | RF2 IN | RF input of the power stage. This pin is internally connected to the bias circuits. An external DC blocking capacitor is required. This same capacitor can also be used for interstage matching. Typically this capacitor is between RF2 IN (pin 5) and RFl OUT (pin 6); see the application schematics for details. | | | 6 | RFl OUT | RF output of the pre-amplifier. Power supply needs to be supplied to this pin through an inductor to Vcc. Together with the series capacitor between pin 5 and 6 the interstage matching circuit is formed. See the application schematics for values for different frequencies. | | | 7 | VCC1 | Positive supply for the active bias circuits. This needs to be bypassed with a single capacitor, placed as close as possible to the package. Additional bypassing of l~F is also recommended, but proximity to the package is not as critical. | | | 8 | RF2 0UT | Amplifier RF output. This is an unmatched collector output of the final amplifier transistor. Pins 8, 9, 13, and 14 are connected internally. Bias for the final power amplifier output transistor must also be provided through one of these two pins. Typically, pins 8 and 9 are connected to a network that provides the DC bias and also creates a second har- monic trap. A capacitor series resonates with internal bond wires and some additional series inductance, and acts as a trap at two times the operating frequency, effectively shorting out the second harmonic. Shorting out this harmonic serves to increase the amplifier's maximum output power and efficiency, as well as to lower the level of the second harmonic output. Typically, pins 13 and 14 are externally connected very close to the package and used as the RF output with a matching network that presents the optimum load impedance to the PA for maxi- mum power and efficiency, as well as providing DC blocking at the out- put. | | | 9 | RF2 0UT | Same as pin 8 | | | 10 | GND | Same as pin 2 | | | 11 | GND | Same as pin 2 | | | 12 | GND | Same as pin 2 | | | 13 | RF2 0UT | Same as pin 8 | | | 14 | RF2 0UT | Same as pin 8 | | | | | |
