8 / 9 page 8 EDS-101432 Rev H Phone: (800) SMI-MMIC http://www.sirenza.com 303 S. Technology Court, Broomfield, CO 80021 SPA-2318 1700-2200 MHz 1 Watt Power Amp. Pin # Function Description 1 VC1 VC1 is the supply voltage for the first stage transistor. The configuration as shown on application schematic is required for optimum RF performance. 2 Vbias Vbias is the bias control pin for the active bias network. Recommended configuration is shown in the Application Schematic. 3 RF In RF input pin. This pin requires the use of an external DC blocking capacitor as shown in the Application Schematic. 4 VPC2 VPC2 is the bias control pin for the active bias network for the second stage. The recommended configuration is shown in the Application Schematic. 5, 6, 7, 8 RF Out/VC2 RF output and bias pins. Bias should be supplied to this pin through an external RF choke. Because DC biasing is present on this pin, a DC blocking capacitor should be used in most applications (see application schematic). The supply side of the bias network should be well bypassed. An output matching network is necessary for optimum performance. EPAD Gnd Exposed area on the bottom side of the package needs to be soldered to the ground plane of the board for thermal and RF performance. Several vias should be located under the EPAD as shown in the recommended land pattern (page 9). 2 3 5-8 ACTIVE BIAS NETWORK ACTIVE BIAS NETWORK 2 4 1 Simplified Device Schematic Caution: ESD sensitive Appropriate precautions in handling, packag- ing and testing devices must be observed. Absolute Maximum Ratings Parameter (Ta = 25ºC) Absolute Limit Max. Supply Current (I C1) at VCC typ. 150 mA Max. Supply Current (I C2) at VCC typ. 750 mA Max. Device Voltage (V CC) at Icc typ. 6.0 V Max. RF Input Power 16 dBm Max. Junction Temp. (T J) +160 ºC Max. Storage Temp. +150 ºC Operation of this device beyond any one of these limits may cause permanent damage. For reliable continuous operation, the device voltage and current must not exceed the maximum operating values specified in the table on page one. Bias Conditions should also satisfy the following expression: I CCVCC (max) < (TJ - TL)/Rth,j-l The Moisture Sensitivity Level rating for this device is level 1 (MSL-1) based on the JEDEC 22-A113 standard classification. No special moisture packaging/handling is required during storage, shipment, or installation of the devices. |
