MEQ14-3ASM
Passive GaAs MMIC 3 GHz Equalizer
The MEQ14-3ASM is a passive GaAs MMIC equalizer in a 3x3 mm QFN package, designed to compensate for frequency-dependent loss from cables, PCB traces and amplifier gain roll-off in RF/microwave and high speed digital systems. It provides 14 dB of positive slope from DC to 3 GHz, with 0.9 dB typical insertion loss at 3 GHz and 27 dB typical return loss across the band. GaAs MMIC technology provides consistent unit-to-unit performance in a small form factor.
| Parameter | Typ | Unit |
|---|---|---|
| Frequency Range | 0 to 3 | GHz |
| Return Loss | 27 | dB |
| Insertion Loss | 0.9 | dB |
| Insertion Loss at DC | 14.7 | dB |
Summary only – refer to the Electrical Specifications, Absolute Maximum Ratings, and Recommended Operating Range tables for complete details.

Equalizer is symmetrical. Reverse measurement is equivalent to forward measurement. All measurements taken in eval board without de-embedding.
The Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. If these limits are exceeded, the device may be inoperable or have a reduced lifetime.

A top-down view of the MEQ14-3ASM package outline drawing is shown below. The MEQ equalizers are symmetrical allowing Port 1 or Port 2 to be used as the input.
| Port | Function | Description | DC Equivalent Circuit |
|---|---|---|---|
| GND | Ground | SM package ground path is provided through the ground paddle. |  |
| Pin 1 | RF Input / Output | Port 1 is DC connected to ground through a resistor. DC block is required if voltage present. |  |
| Pin 9 | RF Input / Output | Port 2 is DC connected to ground through a resistor. DC block is required if voltage present. | |
