Description and Introduction

1.2GHz VCO with Linear Modulation Input The MAX2754EUA is a high-performance, monolithic voltage-controlled oscillator (VCO) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Frequency Range:** 2400 MHz to 2500 MHz  
- **Supply Voltage:** 2.7V to 5.5V  
- **Current Consumption:** 8.5 mA (typical)  
- **Output Power:** -4 dBm (typical)  
- **Phase Noise:** -110 dBc/Hz at 1 MHz offset (typical)  
- **Tuning Voltage Range:** 0.4V to 2.4V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX  

### **Descriptions:**  
The MAX2754EUA is a fully integrated VCO designed for wireless communication applications, including WLAN, Bluetooth, and other 2.4 GHz ISM band systems. It combines a high-frequency oscillator with a varactor diode tuning circuit, eliminating the need for external resonators. The device provides stable frequency output with low phase noise and high linearity.  

### **Features:**  
- **Fully Integrated VCO:** No external resonator required.  
- **Low Phase Noise:** Optimized for wireless applications.  
- **Wide Supply Voltage Range:** Supports 2.7V to 5.5V operation.  
- **Low Power Consumption:** 8.5 mA typical supply current.  
- **High Output Power:** -4 dBm typical for direct RF applications.  
- **Compact Package:** 8-pin µMAX for space-constrained designs.  
- **On-Chip Buffered Output:** Ensures stable performance.  

The MAX2754EUA is ideal for applications requiring a compact, high-performance VCO with minimal external components.

Application Scenarios & Design Considerations

1.2GHz VCO with Linear Modulation Input

Alternative Part Number

  • LTC1569-7CS8 --: Pin-compatible 7th-order low-pass switched-capacitor filter in SO-8, functionally similar to the MAX2754 with comparable cutoff range and supply voltage.
  • AD8620ARZ --: Low-noise precision op-amp in SO-8 that can implement equivalent active filtering stages when the MAX2754 filter function is not strictly required.
  • MF10CCN --: Universal switched-capacitor filter building block in DIP/SO that can be configured to replicate the MAX2754 low-pass response with external resistors.
  • TL072CDR --: Widely available low-noise JFET-input op-amp that can replace the MAX2754 in many general-purpose analog filter circuits at lower cost, though bandwidth and supply range should be verified.
