Device Overview
General Description
The APM-7098 is a broadband distributed, low phase noise LO driver amplifier designed to provide a saturated +23 dBm output power with low DC power consumption. This amplifier uses GaAs HBT technology for low phase noise, and is optimized to provide enough power to drive the LO port of an S-diode mixer from 100 MHz to 18 GHz or of an H or L diode mixer from 100 MHz to 22 GHz. This amplifier can be operated with a variety of bias conditions for both low power and high-power applications.

Port Functions
| Port | Function | Description | DC Equivalent Circuit |
|---|---|---|---|
| CAP1 | Off-Chip Cap Port 1 | CAP1 is a pad that allows the user to attach additional off chip bypass capacitance to the VC supply line. A 0.1µF capacitor is recommended |  |
| CAP2 | Off-Chip Cap Port 2 | CAP2 is a pad that allows the user to attach additional off chip bypass capacitance to provide adequate AC grounding termination. A 0.1µF capacitor is recommended |  |
| GND | Ground | Backside of the IC must be connected to a DC/RF ground with high thermal and electrical conductivity. |  |
| RF In | RF Input | This is the RF Input port of the amplifier die. It is RF matched to 50 Ω, and is DC coupled. RF input pad is GSG with 175 µm pitch. |  |
| RF Out/VC | RF Output and Collector Supply Port | This is the amplifier die’s RF Output and positive VC supply voltage port. It is RF matched to 50 Ω and is DC coupled. RF output pad is GSG with 175 µm pitch. Must have less than 7:1 VSWR when operating with voltage larger 8V on VC |  |
| VB | Current Mirror Bias Port | Port VB is the DC voltage bias pad for the current mirror that control the collector current supplied to the amplifier. Larger voltages result in a higher current draw through port RF Out/VC, effectively functioning as a gain control pin of the amplifier. See section 3.6 for performance at different bias conditions. |  |

Recommended Operating Conditions
The Recommended Operating Conditions indicate the limits, inside which the device should be operated, to guarantee the performance given in Electrical Specifications Operating outside these limits may not necessarily cause damage to the device, but the performance may degrade outside the limits of the electrical specifications. For limits, above which damage may occur, see Absolute Maximum Ratings.
