Device Overview
General Description
The APM-7098SM is a broadband 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 20 GHz or of an H or L-diode mixer from 100 MHz to 30 GHz. This amplifier can be operated with a variety of bias conditions for both low and high-power applications. The APM-7098SM is packaged in a compact 4 mm QFN for surface mount integration on circuit board-based systems.

Port Functions
| Port | Function | Description | DC Equivalent Circuit |
|---|---|---|---|
| 10 | Off-Chip Cap Port 2 | Port 10 allows the user to attach additional off chip bypass capacitance to provide adequate low frequency AC grounding termination to the input matching network. The value should be at least 100nF. |  |
| 12 | Current Mirror Bias Port | Port 12 is the DC voltage bias pad for the current mirror that controls the collector current supplied to the amplifier. See section 3.6 for performance at different bias conditions |  |
| 15 | RF Output and Collector Supply Port | This is the amplifier’s RF Output and positive VC supply voltage pin. It is RF matched to 50 Ω and is DC coupled. Must have less than 7:1 VSWR when operating. |  |
| 23 | Off-Chip Cap Port 1 | Port 23 allows the user to attach additional off chip bypass capacitance to provide adequate low frequency AC grounding termination to the input matching network. The value should be at least 100nF. |  |
| 5 | RF Input | This is the RF input port of the device, and is RF matched to 50 Ω. This port is DC-coupled, and requires a blocking capacitor. | |
| GND | Ground | IC backside must be connected to a DC/RF ground with high thermal and electrical conductivity. |  |
