This FLEX paging receiver board is a high performance RF/IF front–end for using in FLEX pager. This board employs Motorola’s high frequency transistors MMBR941 as well as its M–ary FSK FM IF receiver MC2800 as the core. The whole board includes a LNA, an oscillator, a mixer and a FSK IF receiver. Features:

• Input RF Frequency: 284.14 MHz
• Excellent Sensitivity: –124 dBm
• Operating Voltage: VCC = 1.1 to 1.7 V
• Total Current Consumption: 3.2 mA @ VCC = 1.1 V
• Switchable Bit–Rate Filter to Support All Kinds of FLEX Data Rate
• Separate Interfacing Supply Voltage
