Device Overview
General Description
The ADM-10703PSM is a broadband low noise amplifier covering 3 GHz to 30 GHz. Optimized for low power operation in space-constrained designs, it runs on a single 3 V supply at 40 mA bias current, providing 10.8 dB of small-signal gain with a typical noise figure of 3.3 dB. The ADM-10703PSM requires no application circuit other than bypass capacitors on the DC supply lines, which simplifies integration and minimizes board footprint. Packaged in a compact 3 mm QFN, it is ideal for wideband front-end applications where moderate gain and low added noise are critical. Measured small-signal S-parameters are available to support accurate system simulation.

Port Configuration and Functions
Port Functions
| Port | Function | Description | DC Equivalent Circuit |
|---|---|---|---|
| GND | 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 11 | Vd | Pin 11 is the DC bias supply for the amplifier. The voltage at this pin should be set to 3V 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 1,3,4,5,6,7,9,10,12 | Ground | These pins are not internally connected to the amplifier die. It is recommended to connect these pins to ground to provide RF isolation and mechanical stability. See the recommended landing pattern for details. Datasheet performance was measured with these pins connected to GND. | - |
| Pin 2 | RF Input | Pin 2 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. |  |
| Pin 8 | RF Output | Pin 8 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. |  |
