The ADM-11124PSM is a surface-mount, broadband gain block amplifier designed to operate from 2 to 20 GHz. Its broad bandwidth, 24.4 dB typical small signal gain, and low noise figure of 2.4 dB make it a strong fit for electronic warfare systems requiring wideband signal coverage. The device is internally matched to 50 ohms at both input and output, and requires only a single bypass capacitor on the DC supply line, simplifying integration and reducing board space. It operates from a single 4V supply drawing just 47 mA, with no sequencing requirements for power-up or power-down. The ADM-11124PSM is packaged in a compact 4 x 4 mm plastic QFN for easy integration with automated assembly processes.

Below is the recommended application circuit for the ADM-11124PSM. This is the configuration that is used to characterize this device. However, each PCB layout and environment are different which may require minor modifications of the biasing network. Please contact [email protected] for more information.
| Port | Function | Description | DC Equivalent Circuit |
|---|---|---|---|
| Ground Paddle | Ground | Ground paddle and non-connected pins must be connected to a DC/RF ground potential with high thermal and electrical conductivity, and low inductance. |  |
| Pin 13 | RF Output | Pin 13 is the amplifier's RF output pin. This port is internally matched to 50 Ohms and is internally DC shorted to GND. This pin may be left floating if no DC is present on the line but should be DC blocked otherwise. |  |
| Pin 17 | Vd | Pin 17 is the DC bias supply for the amplifier. The voltage at this pin should be set to 4V for normal operation. This part requires an off-chip bypass capacitor of 0.1uF installed at this pin as close to the IC as possible. See applications circuit. |  |
| Pin 3 | RF Input | Pin 3 is the amplifier's RF input pin. This port is internally matched to 50 Ohms and is internally DC shorted to GND. This pin may be left floating if no DC is present on the line but should be DC blocked otherwise. |  |
