General Description
MB54609 General Description
The MB54609 is an intermediate-frequency (IF) quadrature modulator IC incorporating a 1.0-GHz up-converter optimized for use in digital mobile telecommunication systems such as GSM and PDC (Personal Digital Cellular).
The MB54609 incorporates a quadrature modulator for IF modulation, a transmission up-convert mixer, and a F/F type phase shifter as well, capable of handing IFs in a broad band.
In addition, the MB54609 operates at a low power supply voltage of 3.0 V and a low power supply current of 18 mA (both as typical values), contributing to saving the power consumption of the device.
MB54609 Maximum Ratings
| Parameter | Symbol | Rating | Unit | Remarks |
| Power supply voltage | VCC | 0.5 to 5.0 | V | |
| Output voltage | VO | 0.5 to VCC + 0.5 | V | |
| Input voltage | VI | 0.5 to VCC + 0.5 | V | |
| Open collector applied voltage | VOC | VCC ± 0.3 (0.5 to 5.0) |
V | RFout pin Do not leave this pin open. |
| Output current | IO | ±10 | mA | |
| Storage temperature | Tstg | 55 to +125 | °C |
For normal operation, the device should be used under the recommended operating conditions.
Exceeding any of the recommended conditions may adversely affect LSI reliability.
Note: Although the MB54609 contains an antistatic element to prevent electrostatic breakdown and the circuitry
has been improved in electrostatic protection, observe the following precautions when handling the device:
• When storing or carrying the device, put it in a conductive case.
• Before handling the device, check that the jigs and tools to be used have been uncharged (grounded) as
well as yourself. Use a conductive sheet on the working bench.
• Before fitting the device into or removing it from the socket, turn the power supply off.
• When handling (such as transporting) the MB54609 mounted board, protect the leads with a conductive
sheet.
MB54609 Features
• Incorporating a high-performance transmission mixer covering the entire frequency band of up to 800 MHz used
for PDC services (Maximum output frequency of 1.1 GHz)
Maximum output frequency: 1.1 GHz, Output level: 9 dBm (typical)
• Externally connecting the quadrature modulator with the transmission mixer, allowing a bandpass filter (BPF)
to be inserted in between
The quadrature modulator output can drive a 50 load.
• Flip-flop phase shifter capable of handling intermediate frequencies in the broad band (100 to 800 MHz)
• Operation at low voltage: 2.7 to 3.0 to 3.3 V
• Low current consumption
During operating: 18.0 mA (typical)
In power save mode: 0.6 mA (typical)
• Operating temperature range: Ta = 20 to +85°C
