TRF37T05 300-MHz to 4-GHz Quadrature Modulator
1 Features
3 Description
•
The TRF37T05 is a low-noise direct quadrature
modulator with exceptional TDD performance. It is
capable of converting complex modulated signals
from baseband or IF directly up to RF. The
TRF37T05 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.

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 RF output block consists of a differential-tosingle-ended converter that is capable of driving a
single-ended 50-Ω load. The TRF37T05 requires a
0.25-V common-mode voltage for optimum linearity
performance. The TRF37T05 also provides a fast
power-down pin that can be used to reduce power
dissipation while maintaining optimized adjusted
carrier
feed-through
performance
in
TDD
applications.
