Data sheet
TRF3705
- High Linearity:
- Output IP3: 30 dBm at 1850 MHz
- Low Output Noise Floor: –160 dBm/Hz
- 78-dBc Single-Carrier WCDMA ACPR
at –10-dBm Channel Power - Unadjusted Carrier Suppression: –40 dBm
- Unadjusted Sideband Suppression: –45 dBc
- Single Supply: 3.3-V Operation
- 1-bit Gain Step Control
- Fast Power-Up/Power-Down
The TRF3705 is a low-noise direct quadrature modulator, capable of converting complex modulated signals from baseband or IF directly up to RF. The TRF3705 is a high-performance, superior-linearity device that is ideal to up-convert to RF frequencies of 300 MHz (Note: appropriate matching network is required for optimal performance at 300 MHz) through 4 GHz. The modulator is implemented as a double-balanced mixer.
The RF output block consists of a differential-to-single-ended converter that is capable of driving a single-ended 50-Ω load. The TRF3705 requires a 0.25-V common-mode voltage for optimum linearity performance. The TRF3705 also provides a fast power-down pin that can be used to reduce power dissipation in TDD applications.
The TRF3705 is available in an RGE-24 VQFN package.
