外观1,只有一个WAN和一个LAN口,电源是12V的,5.5*2.5接口。WAN口带POE功能,可以直接网线供电,48V标准POE设备。
新版的数码之家上传照片方便了,支持html5上传,5M以下照片都行,之前老版本得自己降低分辨率,已经好几年没发过帖子了
几个指示灯,分别是GSM/WIFI/WAN/LAN/POWER
拆开后是上下两块板子在一块,螺丝在底部脚垫那,找一圈没发现直接撬开了:lol:
照片比较乱,这个是全部拆开后的照片
WLAN跟DCS1800射频部分,上边是手机信号部分,下边是wlan
两块板子背部,有一个手机卡插槽不知道干什么用的
WLAN部分,AR9341,16M的FLASH,内存不知道多大
1800M手机信号部分
上边是16M的flash,下边是TI的AFE7222I数模转换ADC,Dual 12-Bit, 65 MSPS ADC with dual 12-Bit, 130 MSPS DAC and auxilliary ADC and DACs 64-VQFN -40 to 85,链接里是PDF资料,先复制几段
The AFE7225/7222 is an analog front end designed for full- or half-duplex radios. Over-sampling transmit
12-bit DACs provide output frequencies from baseband to Nyquist. Under-sampling receive 12-bit ADCs
allow analog inputs from baseband to ~230MHz. Most blocks within the AFE7225/7222 are independently
controlled for optimization of power consumption versus utilization. Two auxiliary control 12-bit DACs and
a dual input auxiliary monitoring 12-bit ADC are available via serial interface. Digital features include QMC
(quadrature modulation correction), interpolation, decimation, RMS/peak power meter and mixers with
independent NCOs for RX and TX path.
上边小的是TPS73701,1A的LDO。Single Output LDO, 1A, Adj. (1.2 to 5.0V), Reverse Current Protection
下边大的是德仪的TRF371125IRGZ,0.7 - 4.0 GHz Wide Bandwidth Integrated Direct Down Conversion Receiver
he TRF371125 is a highly linear and integrated direct-conversion quadrature demodulator. The TRF371125 integrates balanced I and Q mixers, LO buffers, and phase splitters to convert an RF signal directly to I and Q baseband. The on-chip programmable-gain amplifiers allow adjustment of the output signal level without the need for external variable-gain (attenuator) devices. The TRF371125 integrates programmable baseband low-pass filters that attenuate nearby interference, eliminating the need for an external baseband filter.
左上角ADF4350,ADF4350结合外部环路滤波器和外部基准频率使用时,可实现小数N分频或整数N分频锁相环(PLL)频率合成器。ADF4350具有一个集成电压控制振荡器(VCO),其基波输出频率范围为2200 MHz至4400 MHz。此外,利用1/2/4/8/16分频电路,用户可以产生低至137.5 MHz的RF输出频率。对于要求隔离的应用,RF输出级可以实现静音。静音功能既可以通过引脚控制,也可以通过软件控制。同时提供辅助RF输出,且不用时可以关断。

最右边TPS65251 TPS65251 4.5-V to 18-V Input, High-Current, Synchronous Step-Down Three BuckSwitcher With Integrated FET
TTL接口和SIM卡插槽,下边是射频部分,双面都是散热片,被动散热的
POE供电部分,还是TPS65251
主板加电ttl打印信息,VxWorks系统
启动之后一直重复的信息
这个是射频部分TTL信息
wlan的信号还不错
还是主板启动后的输出信息
web页面,地址有俩,192.168.119.6/192.168.119.7,用户名admin,密码123456,一个是能设置wlan的,一个是设置手机信号的,可惜不懂怎么用,设置项很多,都是截图
