步骤 107, 生产装配将效率指标不符合规格的功放标准工作电压向 上微调， 直到效率指标符合规格为止。
步骤 108, 生产装配利用步骤 106或步骤 107调整后获得的功放电 压值更新射频模块中存储的射频功率与功放电压值的对应关系。
为了提高生产效率， 对写入和调整后的射频功率与功放电压值的对 应关系还要进行定期维护和更新。 因为， 每个生产批次的射频模块的射 频功率与功放电压值的对应关系都有一个数据标准， 用于表现该射频功 率与功放电压值的对应关系的趋势， 一般一个生产批次的射频模块的射 频功率与功放电压值的对应关系基本上都一样， 而一个生产批次会维持 几个月的生产量。 因此， 如果及时更新该批次的射频模块的射频功率与 功放电压值的对应关系， 那么后面生产的射频模块的调节情况会很少， 因此可以提高生产效率。 为了使用方便， 可以生成功放电压参数表， 将射频功率与功放电压 值的对应关系写入功放电压参数表中， 并定期维护和更新该功放电压参 数表。
参见图 2, 图 2为本发明使功放支持多功率的射频模块的较佳实施 例的结构图。 该射频模块包括： 电源控制模块 201、 电源模块 202、 功 放模块 203、 基带板信号到射频信号的转换模块 204以及天线线性设备 205。
其中， 基带板信号到射频信号的转换模块 204用于将基带板分配的 下行数据转换为射频信号； 天线线性设备 205用于将功放模块放大的射 频信号发送到天线。
电源模块 202为可调电源模块， 其包括电源控制部分 206、 功放电 源 207、 以及存储模块 208。 本实施例中的电源控制部分 206可以用可 调芯片实现。
存储模块 208与电源控制模块 201通过总线相连； 电源模块 202中 的电源控制部分 206通过总线与电源控制模块 201相连； 功放电源 207 通过电源线与电源控制部分 206相连； 功放电源 207与功放模块 203相 连， 为功放模块 203供电。
存储模块 208用于存储射频模块从基带板接收的参数载波 n、 每载 波功率等级 Ln、省电模式开关量、生产装配写入射频模块的功放电压参 数表以及电源模块 202的信息， 包括电压控制字计算系数等；
电源模块 202中的电源控制部分 206用于将电源控制模块 201输出 的电压控制字设置为功放电源 207的输出电压。
电源控制模块 201的功能包括：
1 )从存储模块 208中获取省电模式开关量，确定是否开启省电模式， 即是否选择支持多功率的功放。 该省电开关量是一个用 16机制数表示 的软件标记， 一般可以用 0表示关， 1表示开。
2 )根据从存储模块 208中获取的省电开关量确定是否需要根据存储 模块 208保存的射频参数计算发射功率， 以及从功放电压参数表中读取 功放电压值的方式， 如果读取成功， 则将读取的电压值设置为功放电压 Vout; 否则将功放电压 Vout设置为默认值。
3 )从电源模块的存储模块 208中读取电压控制字计算系数 K、 Β的 值， 如果读取失败， 设置 Κ、 Β为默认值， 并根据确定的 Κ、 Β值， 利 用公式 Vc=K X Vout+B , 计算电压控制字 Vc。
4 )将计算得到的电压控制字输出到电源控制部分 206, 通过电源控 制部分 206设置为功放电源 207的输出电压， 实现对功放电源输出电压 的控制。
本实施例中的存储模块 208设置在电源模块 202中， 在实际应用中 存储模块 208也可以设置在电源模块 202外， 或者部分设置在电源模块 202中， 部分设置在电源模块 202外。
参见图 3 , 图 3为本发明使功放支持多功率的方法的较佳实施例的 流程图。 该方法利用图 1所示的方法， 预先在射频模块的存储模块中存 放了写入射频功率和功放电压值的对应关系的功放电压参数表， 该流程 包括以下步骤：
步骤 301 ,射频模块接收基带板下发的射频参数，包括：参数载波 n、 每载波功率等级 Ln和省电模式开关量， 并将这些参数保存到自身的存 储模块中。
步骤 302, 电源控制模块从存储模块中获取省电模式开关量， 确定 是否打开省电模式。
省电开关量由基带板下发，是一个用 16进制数表示的软件标记，一 般可以用 0表示关， 1表示开。 如果为关， 则执行步骤 307; 否则， 执 行步骤 303。
步骤 303, 电源控制模块根据存储模块保存的射频参数计算发射功 率， 在本实施例中射频参数包括： 载波数和载波功率等级， 计算发射功 率即计算发射功率等级。
假设发射功率等级为 L,则 L可以用公式： L= - 100 log(10A(Ll/( - 100))+...+10A(Ln/( - 100))计算， 其中， Ll~Ln取值范围都是 0~100。
这里采用发射功率等级来表示发射功率的前提是在调试过程中存储 的是对应发射功率等级的功放电压值， 即功放电压参数表中存储的是不 同发射功率等级及其对应的功放电压值。
步骤 304, 电源控制模块根据计算所得的发射功率等级到存储模块 中的功放电压参数表中查询相应的功放电压值， 如果查询成功， 则执行 步骤 305; 否则执行步骤 306。
步骤 305, 电源控制模块将功放电压 Vout设置为查询到的功放电压 值， 执行步骤 308。
步骤 306, 电源控制模块将功放电压 Vout设置为默认值， 执行步骤
308。
步骤 307, 电源控制模块从存储模块中的功放电压参数表中读取第 一个功放电压值， 并将功放电压 Vout设置为该值。
步骤 308-309, 电源控制模块从存储模块中读取 K、 Β值， 如果读取 成功， 则执行步骤 311; 否则执行步骤 310。
步骤 310, 电源控制模块将 、 Β设置为默认值。
存储模块一般为 E2PROM, E2PROM是物理器件， 可能因为读写次 数有限而失效或者由于总线忙而出现异常情况， 这样就会使电源控制模 块读取 E2PROM失败， 因此为了保证电源控制模块实现流程的连续性， 在电源控制模块中设置了 Κ、 Β的默认值， 当电源控制模块读取 Κ、 Β 失败时， 将采用默认值进行计算。
步骤 311 ,电源控制模块利用步骤 308-309或 310中确定的 K、 Β值， 步骤 305或 306或 307设置的功放电压值 Vout,以及公式 Vc=K χ Vout+B , 计算电压控制字 Vc, 并将其输出到电源模块的电源控制部分。
步骤 312, 电源模块的电源控制部分利用步骤 311计算所得的电压 控制字 Vc的值设置功放电源的输出电压， 从而达到调整功放电源电压 的目的。
功放电源电压调整后， 根据电流电压得到功率的原理， 即功率 =输 入电压 X输入电流， 则在功放模块的输入电流不变的情况下， 调整功放 模块的输入电压就可以达到调整其功率的目的。
从以上实施例可见， 本发明实施例通过对射频模块和功放模块进行 调试， 再经过老化处理和指标测试过程获得发射功率与功放电压值之间 的对应关系， 并将该对应关系存储到射频模块中。 同时， 在射频模块中 设置电源控制模块， 将射频模块中的电源模块设置为可调电源模块， 以 使得射频模块可以根据计算所得的发射功率以及存储的不同发射功率 对应的功放电压值调整为功放模块提供的电压值， 进而达到使功放支持 多功率的目的。
另外， 本发明实施例提供的测试方法还可以根据需要实时更新射频 总之， 本发明实施例提供的方法和射频模块可以根据当前的应用需 求， 通过调整电源模块为功放模块提供的输出电压， 使同一功放能够支 持多种发射功率， 满足不同的应用需求， 从而不必再生产和维护具有不 同发射功率的功放， 极大提高了功放使用的灵活性， 降低了功放维护成 本以及功放生产和使用的复杂度。
