TRF3701IRHC

Product Overview

TRF3701IRHC from Texas Instruments is a low-noise direct quadrature RF modulator. This product detail focuses on modulator architecture, operating frequency range, baseband or control interface, package style and practical sourcing considerations.

The summary is written for engineering and purchasing teams evaluating RF modulator replacement parts or BOM sourcing options, without copying catalog text or internal stock notes.

Key Features

• Manufacturer: Texas Instruments
• Part Number: TRF3701IRHC
• Device Type: low-noise direct quadrature RF modulator
• Modulator Architecture: Direct I/Q quadrature modulator implemented with a double-balanced mixer and internal LO phase splitter
• RF Frequency Range: 0.14 GHz to 1.5 GHz family range; TRF3701 is commonly used up to 1.5 GHz RF output
• Baseband Interface: Differential I and Q baseband inputs for direct conversion from baseband or IF to RF
• LO Interface: Single-ended LO input with internal quadrature phase splitter
• RF Output: Internal analog combiner sums I and Q RF outputs and can drive an RF preamplifier directly
• Package / Case: 16-pin RHC QFN package family; tape/reel or tray suffix follows TI ordering code
• Operating Temperature: -40°C to +85°C industrial range for TRF3701IRHC ordering option
• Design Notes: Match the I/Q baseband common-mode, LO drive and RF output matching to the selected TRF3701 suffix.

Applications

Wireless transmitters, base-station transmit chains, direct-conversion RF cards and legacy modulator replacement projects.

Designs that need a discrete I/Q modulator between DAC/baseband circuitry and the RF driver or power amplifier.

Quality & Sourcing

Antrex Electronics can support sourcing for TRF3701IRHC through available stock checks, BOM consolidation and alternative-lot review. For RF modulator ICs and modules, package condition, date code, MSL handling and original labeling should be checked before shipment.

For shortage support, legacy repair or project builds, Antrex Electronics can coordinate visual inspection, packaging verification and third-party electrical or authenticity testing when required. This helps buyers manage risk when sourcing discontinued, allocated or hard-to-find RF modulator parts.
