Description

The LTC5599 is a direct conversion I/Q modulator designed for low power wireless applications that enable direct modulation of differential baseband I and Q signals on an RF carrier.

Single side-band modulation or side-band suppressed upconversion can be achieved by applying 90° phase-shifted signals to the I and Q inputs.

The I/Q baseband input ports can be either AC or DC coupled to a source with a common mode voltage level of about1.4V.

Features : 

1. Frequency Range: 30MHz to 1300MHz

2. Low Power: 2.7V to 3.6V Supply; 28mA

3. Low LO Carrier Leakage: –51.5dBm at 500MHz

4. Side-Band Suppression: –52.6dBc at 500MHz

5. Output IP3: 20.8dBm at 500MHz
