Device Overview
General Description
The ADM-11122PSM is a surface-mount, wideband, high output IP2, gain block amplifier designed to operate from 2 to 20 GHz. It provides 19 dB typical small-signal gain across the band, along with 4.2 dB typical noise figure and 13.7 dBm typical output P1dB. The amplifier also delivers 55 dBm typical output IP2, making it well suited for direct-conversion EW systems and other wideband signal chain applications where gain and second-order linearity are critical. The device is internally matched to 50 ohms at both input and output, and operates with a +4 V supply voltage, drawing just 84 mA. The ADM-11122PSM is packaged in a compact 4 x 4 mm plastic QFN for easy integration with automated assembly processes.

Port Configuration and Functions
Port Functions
| 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. |  |
