Description and Introduction

Low-Voltage 1.2-GHz Fractional-N/Integer-N Synthesizer 20-TSSOP 0 to 70 The TRF2056 is a low-noise amplifier (LNA) manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Frequency Range:** 50 MHz to 4000 MHz  
- **Noise Figure:** 0.9 dB (typical at 900 MHz)  
- **Gain:** 18 dB (typical at 900 MHz)  
- **Input IP3 (Third-Order Intercept Point):** +20 dBm (typical)  
- **Supply Voltage:** 3 V to 5 V  
- **Current Consumption:** 20 mA (typical at 3 V)  
- **Package:** 6-pin SOT-23  

### **Description:**  
The TRF2056 is a high-performance, broadband LNA designed for applications requiring low noise and high linearity. It is suitable for cellular, wireless infrastructure, and general RF amplification.

### **Features:**  
- Ultra-low noise figure (0.9 dB typical)  
- High gain (18 dB typical)  
- Broadband operation (50 MHz to 4 GHz)  
- Single 3 V to 5 V supply operation  
- Integrated active bias for stable performance  
- Small SOT-23 package for space-constrained designs  

This information is sourced from TI's official documentation.

Application Scenarios & Design Considerations

Low-Voltage 1.2-GHz Fractional-N/Integer-N Synthesizer 20-TSSOP 0 to 70

Alternative Part Number

  • NE602AN --: Classic balanced mixer/oscillator IC in DIP-8, functionally similar to the TRF2056 mixer section and widely available as a drop-in style replacement in older receiver designs.
  • SA612AD --: Low-power VHF double-balanced mixer and oscillator, pin-compatible with NE602 family and a common substitute for TRF2056 mixer applications.
  • MC1496P --: Industry-standard balanced modulator/demodulator in DIP-14, usable as a mixer replacement when the TRF2056 is unavailable, though external oscillator circuitry is required.
