Device Overview
General Description
The ADM-8625PC is a high-linearity low noise amplifier capable of providing 18 dB gain, 1.4 dB noise figure and +29 dBm OIP3 from 750 MHz to 8 GHz. The ADM-8625PC can serve either as a linear signal amplifier, or as a saturated driver amplifier for H- or S-diode mixers. The amplifier features excellent return losses, gain flatness and high dynamic range making it suitable for RF front-end applications. The size and low power consumption of the ADM-8625PC make it ideal for low SWaP applications.
Features
- 18 dB typical gain
- 1.4 dB typical noise figure
- Single Supply, Positive Only Bias
- Low power consumption
Applications
- Test and Measurement Equipment
- Radar and satellite communications

Port Configuration and Functions
Port Functions
| Port | Function | Connector Type | Description | DC Equivalent Circuit |
|---|---|---|---|---|
| GND | Ground | - | Housing or ground lug must be connected to a DC/RF ground potential with high thermal and electrical conductivity. |  |
| RF In | RF Input | - | This is the amplifier’s RF Input port. It is RF matched to 50 Ω and has built-in DC blocking capacitors. |  |
| RF Out | RF Output | - | This is the amplifier’s RF Output port. It is RF matched to 50 Ω and has built-in DC blocking capacitors. | |
| Vb | Positive Bias Pin | - | The Vb pin provides a required positive bias which supplies the current mirror. A higher voltage results in a higher current draw through the RF Out port. This pin is nominally set at +5V. |  |
| Vd | Drain Supply Pin | - | The VD pin supplies DC voltage to the drain of the amplifier IC. This pin is nominally set at +5V. |  |

Specifications
Absolute Maximum Ratings
The Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. If any one of these limits are exceeded, the device may become inoperable or have a reduced lifetime. Reliability limits are individual, instantaneous catastrophic limits only. Functional operation limits are indicated below. Operation of the device at multiple absolute maximum limits or for extended periods at a single limit can cause degradation and damage to the device.
